Inverse-Designed Ultra-Compact Passive Phase Shifters for High-Performance Beam Steering [PDF]

open access: yesSensors
Ultra-compact passive phase shifters are inversely designed by the multi-objective particle swarm optimization algorithm. The wavelength-dependent phase difference between two output beams originates from the different distances of the input light ...

Reconfigurable Josephson Phase Shifter [PDF]

open access: yesNano Letters, 2021
Phase shifter is one of the key elements of quantum electronics. In order to facilitate operation and avoid decoherence, it has to be reconfigurable, persistent, and nondissipative. In this work, we demonstrate prototypes of such devices in which a Josephson phase shift is generated by coreless superconducting vortices.

Application of Coherently Radiating Periodic Structures for Feeding Subarrays in Limited-Scan Arrays

open access: yesIEEE Open Journal of Antennas and Propagation, 2023
This paper presents a new design technique to improve the reduction of phase shifters using sub-arrays and CORPS (coherently radiating periodic structures) technology. The CORPS network generates the values of cophasal excitation with reduced input ports.
