We are working on designing RF sensors to detect several vital signs, such as Blood Glucose. Developing a low-cost, non-invasive blood glucose monitoring system would be life-changing for diabetic patients. 

We propose to develop a first-of-its-kind wearable electromagnetic(EM)-based biosensor that can safely and accurately detect the changes in the dielectric properties (e.g., glucose level) of the blood through the transmission and reflection of EM waves. 

Millimeter-waves (mm-wave) is a promising technology to provide high data rates (multi-Gb/s) for short-range communication. My research has been focused on the 60 GHz band. However, this new mm-wave system requires smaller, high-efficiency front-ends and antennas. We are working to employ ridge gap waveguide (RGW) technology for the antenna design to feed several planar antenna arrays and dielectric resonator antenna (DRA).

Dielectric measurement is an effective tool for analyzing material behavior, particularly at high frequencies, since it provides the electrical or magnetic properties of the material, which is a vital parameter required to utilize the material in many applications. The measurement of the dielectric characteristics of materials is crucially significant, especially in research areas such as material science, communication, and microwave circuit design. We are exploring several methods of dielectric measurements, such as free space and open-ended coaxial probe methods.
