Active Research Topics
GRIN Lenses for Millimeter-wave Communications and Sensing
We are investigating new fully analog solutions to the problem of multi-beam, wideband, millimeter-wave antennas for both base stations and mobile devices.
Dynamically Reconfigurable RF Circuits and Antennas
We have developed a concept for dynamically reconfigurable distributed microwave circuits by leveraging the abrupt conductivity transition in phase-change materials (PCM).
Low-resolution Arrays for 5G/6G Millimeter-wave Communications and Sensing
Co-optimization from the PHY to the NETWORK. Consider materials, devices, circuits, and systems for wideband and low-power millimeter-wave communications and spectrum sensing.
Spectrum Sensing & Geolocation
Hardware and algorithms for an ultra-low-cost ($1), low power (100's millimwatts), distributed spectrum sensor network for emitter geolocation and pervasive spectrum sensing.
Past Research Projects
Analog Signal Processing
We are developing analog signal processing blocks capable of performing e.g., correlation and non-reciprocal functions capable of operating at GHz data rates without Gbps sampling.
Scanning Near-field Microwave Microscopy
SNMM is a method for performing microwave characterization of materials and devices (e.g., permittivity, permeability, conductivity)
Non-foster Matching for High-power Electrically Small Antennas
Distributed non-Foster circuits enable high-power matching of electrically small antennas for transmitter applications that require linearity
