Hybrid Mechanical and Electronic Beam Steering for Maximizing OAM Channel Capacity

Lightweight Mirror Structures for Mechanical Beam Steering

Defense applications ofspace-borne laser radar require a sensor that can point to a large number of targets in rapid succession and over a wide field of regard. By using a fullaperture, mechanically steered flat mirror, the requirements for high-acceleration beam steering can be met. Three alternative mirror structures were designed and their perfonnance was evaluated through computer simulatio...

Conditions for Monopole Antenna Arrangement Mounted on Mobile Terminal for Maximizing Beam-steering and Diversity Gains

Fully integrated hybrid silicon free-space beam steering source with 32 channel phased array

Free-space beam steering using optical phased arrays is a promising method for implementing free-space communication links and Light Detection and Ranging (LIDAR) without the sensitivity to inertial forces and long latencies which characterize moving parts. Implementing this approach on a silicon-based photonic integrated circuit adds the additional advantage of working with highly developed CM...

Beam Steering of Patch Antenna Radiation using Mechanical Meta-Structure

Attempt is made to modify the radiation pattern of a patch antenna using a meta-structure consisting of an array of monopole antennas in the near field. The effect of the metastructure on the radiation characteristics of the patch antenna, for different angular arrangements of the metastructure plates, has been experimentally studied.

Hybrid silicon free-space source with integrated beam steering

Free-space beam steering using optical phase arrays are desirable as a means of implementing Light Detection and Ranging (LIDAR) and free-space communication links without the need for moving parts, thus alleviating vulnerabilities due to vibrations and inertial forces. Implementing such an approach in silicon photonic integrated circuits is particularly desirable in order to take advantage of ...
