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
