| Abstract
|
The talk will focus on selected research areas carried out in the Applied Electromagnetics Group at the University of Calgary. Specifically, we will discuss:
- Re-configurable Antenna Arrays. Antenna arrays that utilize tunable array elements are explored in the group. The research focuses on reflectarrays that use elements such as split patch antennas controlled with high Q varactors. 0-350 degrees phase-shifts at each element were achieved. A prototype antenna was built at 5.5 GHz. Simultaneously, prototypes of re-configurable antennas utilizing MEMS technology are explored
- RF MEMS devices. We are interested in tunable and high Q MEMS RF devices. The talk will describe the devices (fabricated in our custom process) such as: analog, ultra low loss phase shifter, tunable inductors (30% tuning with Q up to 30 and self resonance above 35GHz, in CMOS compatible process), high Q fixed inductors (Q above 100), as well as tunable capacitors and filters.
- Simulation tools. The group has long been involved in development of electromagnetics simulation tools. However, in recent years our focus shifted into development of hardware acceleration of computer codes. We have developed solutions that provide up to an order of magnitude acceleration on inexpensive hardware platforms.
- Breast cancer detection research. We have been involved in all aspects of the breast cancer detection, however in this talk I will mainly focus on a database of breast tissue parameters (developed in collaboration with U. of Wisconsin-Madison). A special precision dielectric probes were developed for the project will also be discussed.
