Abstract

In this research study, we explore the behavior of electromagnetic waves as they propagate through ridge waveguides with convex and concave shapes, having both single and double walls. To analyze the waveguide's characteristics, we employ the highly accurate hp-finite element method (hp-FEM). The focus is on investigating the impact of these ridge deformations on cutoff frequencies and bandpass for TE10 and TE20 modes. To benchmark our findings, we compare the results with those obtained from a conventional x-band rectangular waveguide. Three cases of ridge deformation are considered: a convex-shaped ridge on one side wall, a concave-shaped ridge on one side wall, and a concave-shaped ridge on both side walls. Our comprehensive study aims to gain insights into the electromagnetic behavior of these waveguides and assess their potential applications in high-frequency communication systems and microwave devices.
