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.

The authors would very much like to thank the reviewer of this paper. His comment has added much to the quality and clarity of this paper.

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.
