| Project Title | Super-hydrophobic Surface Design and Fabrication |
| Supervisor(s) | HONG MINGHUI,NA |
| Synopsis | Super-hydrophobic surface with lotus leaf effect was first studied by German scientists in 1979, and lots of following studies had been done since then. In nature, lotus and other plant leaves have super-hydrophobic surfaces with self-cleaning effect. Water droplet does not adhere to lotus leaves and completely rolls off the leaves, carrying away undesirable particles. Super-hydrophobic surface has a wide range of potential applications from solar cell to micro-devices. Patterned super-hydrophobic surfaces also have the potential applications for lab-on-a-chip and micro-fluidic devices, which can drastically improve the surface based bio-analysis. The objective of this project is to study the mechanism of super-hydrophobic materials, such as lotus leaves and understand the concept of surface energy, wetting property, Cassie-Baxter model and Wenzel model. Laser is a flexible processing tool to texture variable material surfaces, like metal, glass and silicon wafers over a large area. Focused high power laser can directly write on the surfaces of materials. Relatively low power laser patterns coating layers on the materials, and then transfers the patterns onto the substrate surfaces. Spraying nano-particles or growing nano-wires can be processed to enhance super-hydrophobic effect. The student will work together with the research staff to carry out the laser micro/nanoprocessing experiment. |

| Project Title | Terahertz Meta-materials Fabrication by Laser Micro-/nano-engineering |
| Supervisor(s) | HONG MINGHUI,NA |
| Synopsis | Meta-materials have attracted great research interest during the past decades due to their unique optical properties in terahertz range. THz wave with its frequency ranging from 0.1 to 10 THz has extensive applications in home security, telecommunication and bio-detection. Meta-materials design, fabrication and application can provide us a wonderful tool to overcome diffraction limit for higher resolution THz wave imaging and spectroscopy, which can diagnose the cancer etc. diseases at their early stages. Meanwhile, meta-materials/structures are proposed to be the promising candidates to control the terahertz beam as cloaking, filter, beam splitter, and polarizer, etc.
The objective of this project is to study the novel resonance property of metamaterials for terahertz applications involving laser micro-/nano-engineering. Laser micro-lens array (MLA) lithography will be applied in the device fabrication, which can realize high-speed, accurate-controlled, and large-area fabrication of arbitrary designed meta-materials in micron and sub-micron scales. Micro-lens array has the advantages to split a single incident laser beam into thousands to millions of tiny light beams to fabricate the meta-materials/structures simultaneously with high efficiency. The meta-materials will be characterized by terahertz time-domain spectroscopy (THz-TDS) which is an advanced technique to analyze the materials’ optical properties in THz region.
The students will have opportunities to learn the operation skills of the laser MLA lithography (working together with higher degree students and research staff) and analysis tools, such as THz-TDS, optical microscope and scanning electron microscope. They can be further trained to do independent works to complete some parts of the above-mentioned research plan.

| Project Title | Design of Multi-Band Antennas |
| Supervisor(s) | GUO YONGXIN,NA |
| Synopsis | Modern wireless communications systems increasingly operate at higher and higher frequencies and cover more and more bands. The trend in the development of wireless personal communication systems has been in the pursuit of a single system that can accommodate the needs of all users. To develop compact, highly efficient and broadband antennas, which are well suited for integration with multi-band multi-functional personal communication transceiver systems, is the most important task for antenna engineers.
The object of this project is to experimentally and numerically carry out one new multi-band planar microstrip antenna. The numerical simulation is based on commonly commercial electromagnetic (EM) software, such as HFSS. The design will be simulated, optimized, and prototyped. Finally, the impedance and radiation performances of the prototype will be measured.

| Project Title | Design of Broadband Microstrip Antennas |
| Supervisor(s) | GUO YONGXIN,NA |
| Synopsis | Microstrip antennas offer attractive features of low profile, light weight, ease of fabrication, conformity to the supporting surface and compatibility with microwave integrated circuits (MICs). If the expense of materials and fabrication is not prohibitive, they can also be low in cost. However, probably the most serious limitation of this technology is the narrow bandwidth of the basic element. The conventional microstrip patch element typically has an impedance bandwidth of only a few percent. For this reason, much of the large volume of research and development in the area of microstrip antennas in the last two decades has been devoted to various techniques for wideband operation of microstrip antennas.
The objective of this project is to explore new methods to develop broadband microstrip antennas. This project includes numerical simulation and experimental measurement. The numerical simulation is based on commonly used commercial electromagnetic (EM) software, such as HFSS. The impedance and radiation patterns measurement will be carried out using our microwave network analyser and EM anechoic chamber. The design will be simulated, optimized, prototyped and measured.

| Project Title | Design of Ultra-Wideband Antennas |
| Supervisor(s) | GUO YONGXIN,NA |
| Synopsis | With the rapid development of the wireless communications, many systems now operate in two or more frequency bands. The ultrawideband (UWB) antennas, which are usually, designed using a single antenna structure with broadband operation, become attractive for the benefits of simpler structure. Here, the UWB antennas mean those with relative impedance bandwidth larger than 25%. Besides, according to the regulations released by Federal Communications Commission, one of the UWB systems has been allocated to the frequency band of 3.1 to 10.6 GHz for the merits of large capacity of data and high speed data transmission rate. Thus, there is a growing demand on antenna design with wideband operation, both for the integration usage of multi-mode multi-frequency systems and for an UWB system.
The objective of this project is to explore new methods to develop ultra-wideband antennas. This project includes numerical simulation and experimental measurement. The numerical simulation is based on commonly used commercial electromagnetic (EM) software, such as HFSS. The impedance and radiation patterns measurement will be carried out using our microwave network analyser and EM anechoic chamber. The design will be simulated, optimized, prototyped and measured.

| Project Title | Simulation of memory resistive switching |
| Supervisor(s) | CHIM WAI KIN,NA |
| Synopsis | The ideal electronic switch is one that is scalable down to atomic dimensions and with negligible power dissipation. Such a device will have potential applications in memory and logic operation. In 2005, Terabe et al. reported such a switching device using silver sulphide, an ionic conductor metal chalocogenide in which electrical conduction is achieved by both electrons and ions. Besides metal chalcogenides, metal oxides, such as nickel oxide and titanium oxide in metal-insulator-metal structures, have also shown resistive switching effects and have been proposed as potential future non-volatile memory devices since they combine the advantages of Flash and DRAM memories and are scalable. These structures typically involve the formation/disruption of a conductive filament and hence are known as fuse/antifuse memory according to the International Technology Roadmap for Semiconductors. Several mechanisms have been proposed to explain the resistive switching phenomenon. The more widely accepted mechanisms include the reduction of migrating metal cations at the cathode resulting in the formation of a conductive filament and the drift of positively-charged oxygen vacancies to form or disperse locally conductive channels.
In this project, the student will develop a FORTRAN simulation program for simulating the resistive switching effect using a percolation model based on a network of circuit breakers with two metastable states. Using the developed program, investigations into resistive switching will be conducted for different bias conditions to gain further insights into the phenomenon.

| Supervisor(s) | WONG WAI CHOONG, LAWRENCE,NA |
| Synopsis | This project aims to investigate methods to determine the location of mobile devices in wireless local area networks (LANs). The approach will be based on capturing the profile of received radio signals at reference access points and analyzing these radio profiles to triangulate the position of mobile devices. Investigations will be made for both line-of-sight and non-line-of-sight scenarios. With the ability to sense the location of the mobile devices, this opens up a wealth of new applications and services. The student will develop an understanding of radio propagation phenomenon and how this will influence location sensing.

The user location can be determined via two different methods, namely through either mobile cell site association or Wi-Fi hotspot association. After registering and updating the user’s location at an appropriate location-based server, queries can be made to ascertain contacts among the user’s social network that may be in close proximity.

Such optical delays should optimally be continuously tunable over a wide range of delay times.
Dispersion can be used for generation of optical delay.

| Supervisor(s) | CHOR ENG FONG |
| Synopsis | A substantial proportion of electrical energy generated (about 20%) is used for lighting. Currently, the most widely used sources of artificial illumination are incandescent and fluorescent lamps. Other types of lamps exist for special applications. In recent years, solid-sate lighting (SSL) devices have surfaced and promise to replace conventional light sources, with much potential in economic and environmental savings. SSL devices are essentially based on light-emitting diodes (LEDs) and have already been adopted as the back light for liquid crystal display (LCD) monitors or televisions, on automobile, traffic lights, etc. In addition to economic and environmental savings, SSL are vibration and shock resistant, and have a longer life time.
In this project, student will first learn of the differences, and pros and cons of using SSL in place of various types of conventional lighting, through which he/she will come to appreciate why SSL presents much potential in economic and environmental savings. Furthermore, he/she will learn of the current status and challenges of SSL. After that, student will need to carry out a cost-and-benefit analysis between the use of SSL and conventional lightings in the number of settings: e.g., (i) a household, (ii) street light, and (iii) a factory/office area. In addition, he/she will need to explore how lighting can be optimized or re-designed using SSL to further enhance the efficiency in electrical energy usage. |
