Mesh Space Mapping for a Three-Pole H-Plane Coupled Cavity Filter With Rounded Corners

Mesh space mapping (MSM) is widely applied in the field of electromagnetic (EM) optimization. In this paper, an MSM approach employing embedded mesh morphing and sharpening structural processing (SSP) techniques is employed to optimize a three-pole H-plane coupled cavity filter with rounded corners. The successful validation of the applicability of this method is demonstrated through the optimization process.
