Conformal Metasurface Antennas for Angle of Arrival Detection
Detecting angle of arrival (AoA) of electromagnetic (EM) signals is a priority for many civil and military applications including navigation, surveillance, and communication systems. The antenna structures typically used for this purpose are required to conform to nearly arbitrary surfaces including robots, cars, aerial vehicles, and missiles. As...

Angle of Arrival Detection using Intensity-Only Data
Many navigation systems rely on detecting the angle of arrival (AoA) of waves to determine desired coordinates. For example, a variety of radar systems deploy AoA detection to deliver desired information about the surrounding area or target of interest. Modern radio environments rely on adaptive beamforming techniques to direct electromagnetic waves...

Clock Skewing for Area and Power Optimization of ASICs Using Differential Flipflops and Local Clocking
Synchronous logic remains the dominant design paradigm of digital systems such as Application Specific Integrated Circuits (ASICs). The conventional design of sequential circuit networks is based on the assumption that every register receives the clock signal at the same time. However, guaranteeing the simultaneity of clock arrival times in practice...

Neural Volumetric Reconstruction for Coherent Synthetic Aperture Sonar
Synthetic aperture sonar (SAS) is an active acoustic imaging technique that coherently combines data from a moving array to form high-resolution imagery, especially of underwater environments. The moving array in SAS collects both magnitude and phase information which allows coherent integration methods to achieve resolution parallel to the sensor...

Low-cost System for Testing Motion/Pressure Sensors
In the domain of accelerometer sensitivity measurement, the current standard relies heavily on the utilization of expensive industrial shakers. These shaker devices generate vibrations in a sinusoidal pattern, which, while effective, pose significant limitations. The oscillating motion they produce, moving between high and low points, introduces challenges...
