We present a method for the mitigation of quantization lobes in single-bit reconfigurable
reflective surfaces (RRSs). Typically, RRSs are planar beamforming structures consisting of …

Millimeter-wave technology has the potential to revolutionize the field of electronic imaging
due to its ability to generate images with high resolution through obscurants like fog and …

Recent developments in fifth-generation (5G) wireless communications networks are
creating an increasingly crowded electromagnetic environment at microwave (3–30 GHz) …

In this article, an active millimeter-wave imaging system using two rectangular waveguide
leaky-wave focusing antennas deployed in a quasi-monostatic transmitter and receiver pair …

We present a dynamic millimeter-wave antenna array with rotational dynamics to detect
shapes in a scene without image formation. The rotationally dynamic two-element receiving …

A photonics-based system for simultaneous angle of arrival (AOA) and frequency
measurement is proposed and demonstrated. In the proposed system, an acousto-optic …

We present a new approach to the classification of scenes in the microwave and millimeter-
wave bands that leverages a novel dynamic antenna array concept to capture distinct …

It has been recently demonstrated that microwave and millimeter-wave imagery can be
obtained using multiple noise transmitters to illuminate the scene with incoherent space-time …

We present a novel approach to millimeter-wave imaging that combines a new dynamic
antenna array concept with active illumination by means of noise signals and interferometric …

In this letter, we propose a frequency-scanning leaky-wave array antenna with a significantly
increased scanning range. The proposed structure consists of a pair of rectangular …
