Abstract: Over-the-Air measurements are critical for the validation and test of active antenna arrays required to operate at mmWave frequencies. In [1] a novel over-the-air near-field measurement ...

Introduction: In this in silico, in vitro, and in vivo study, we propose metrics for the characterization of highly scattering media using backscattered acoustic waves in the MHz range, for ...

LEO constellation systems require electronically steered arrays at both ends of the link, with the payload particularly challenging because it operates in a power-limited environment. Learn how ...

Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. If target is not found in the array, return [-1, -1]. You must write an ...

A 28GHz time-division multiple-input multiple-output (MIMO) receiver with eight radio frequency elements, each occupying just 0.1 mm 2, has been developed by ...

Abstract: Remote optical sensing using laser radiation is being increasing deployed for both military and civilian applications. The technique, commonly known as LADAR or LIDAR, uses an optical range ...
