Electromagnetics, Microwaves and Antennas
Research in the Electromagnetics Microwave and Antenna Laboratory activities include theoretical modeling and measurement of microstrip antennas and integrated microwave circuits, composite right/left handed materials and applications, numerical optimization techniques, and bioelectromagnetics. Recent research projects include the following.
The project is the development of a noninvasive technique for measuring blood glucose levels. The feasibility of monitoring and estimating glucose level in real time using a microstrip antenna strapped on a patient’s arm has been demonstrated successfully. Work under progress is the optimization of the technique with a larger sample of patients
2. Left handed metamaterials and applications:
Negative permittivity or zero permittivity materials known as left handed materials have some unique properties that overcome wavelength size limitations imposed by right handed materials. The Nanoplasmonics and Metamaterials Research group at RIT has created different types of left handed materials which we have implemented for reducing antenna sizes by 70% and for enhancing gain. A variety of projects with LH metamaterials is being pursued.
3. Wireless Medical Telemetry:
This is a collaborative antenna research with the Communications research group. Creeping wave antennas have been designed and constructed for wireless body area networks. Data packets providing received signal strength indicators are used to demonstrate that creeping wave antennas provide reliable on-body communications while significantly reducing inter-network interference.
4. Wireless Network-on-Chip (WNoC):
This is a collaborative project with the Digital Systems Group. the principal aim is to explore methods for achieving thermal efficiency in multicore chips with wireless interconnects for operating at 60GHz. Wireless interconnects have been successfully designed and modeled in a novel 3-D WNoC of different configurations with embedded micro fluidic layers to address the interior heating. It is also shown that there is no transmission at the clock frequencies.
