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...

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...

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...

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...

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...

Burrowing robots are a class of robot that can move themselves in soil for geotechnical site investigation, search and rescue, sensor deployment, inspection, monitoring, and construction purposes. Moving through soil is a challenging problem due to high drag force and complex underground environments. Many organisms adopt well-evolved strategies and...

Multi-robot systems (MRS) composed of multiple mobile robots have been used for various collective exploration and perception tasks, such as mapping unknown environments, disaster response, and surveillance and monitoring. The performance of MRS in such applications is constrained by the capabilities of the payloads that the robots can carry on-board,...
