Ridge waveguide optimization with PSO algorithm

Abstract

A technique of automatic optimization for guiding structures at microwave range is presented. Geometrical parameters have been optimized taking into account conflicting requirements (high bandwidth, high power handling capability and low attenuation constant) with PSO algorithm. Propagation performances are computed with a FDFD technique.

Keywords:

Notes

1 In this work only the power losses due to the finite conductibility of the metallic conductor are considered, since the WGs are hollow.
