Microwave & Radio Frequency


Microwaves and radio-frequency (RF) are at the heart of many electronic applications such as cellular phones, WiFi, RFID, GPS, Radar and satellites etc.. The research efforts of the Microwave & RF faculty staff embrace both hardware implementations and theoretical studies in electromagnetic theory, antennas and RF, microwave and millimeter-wave circuits and systems for various government, industry and defense related applications, e.g. wireless communications, biomedical and healthcare applications, and satellite and space thrusts.The laboratories in the microwave & RF area own the major measurement instruments for microwave circuits, MMICs and antennas, including antenna anechoic chamber (Fig.1), probe station and pulse based DCIV system up to 50 GHz (Fig.2), and VNA (up to 110 GHz) and spectrum analyzer (50 GHz) and signal generator (40 GHz). The laboratories in the microwave & RF area also have various commercial RF circuit and EM simulation tools, e.g. ADS, Microwave Office, HFSS, CST, etc. for RF circuit and antenna designs.

 

Research Focus



Biomedical Electromagnetics


We develop electromagnetic technologies that improve human health. Our researchers are building systems that can wirelessly power implanted medical devices, sensors capable of monitoring physiological parameters in real-time, and wearable antennas that integrate seamlessly with the human body. These technologies will transform the next generation of biomedical devices, and provide new ways to monitor or treat disease.

Wireless Photonic Devices


We design miniaturized photonic devices for wireless light delivery deep into living systems. Applications of these devices include activation or inhibition of neural activity using optogenetics and light-based cancer therapy. These technologies enable highly precise therapies by combining the spatiotemporal control of bioelectronics with the molecular selectivity of light. Image of light emitting-device wirelessly powered in a model of the heart. we aim to engineer fully implantable devices for continuous monitoring and treatment in scientific and translational models of disease.

Translational Wireless Technologies


We study biomedical wireless systems computationally and in large, human-scale animal models. We seek to draw insights from physical principles to develop broad engineering solutions for unmet challenges in system performance. We apply these solutions to demonstrate approaches to wirelessly power and communicate with bioelectronic devices in previously inaccessible regions of the body.
