We demonstrate a 3-dB power splitter optimized by an enhanced particle swarm
optimization algorithm based on a curved directional coupler, with a set of silicon columns …

In this paper, a new method to facilitate the design of Printed Ridge Gap Waveguide
(PRGW) structures is introduced. One of the main difficulties in designing such structures is …
