Analytical Dielectric Constant Sensitivity of Ridge Waveguide Filters

Abstract

Sensitivity of the scattering parameters of ridge waveguide filters with respect to the relative dielectric constant is evaluated analytically. These scattering parameters are obtained with the full-wave mode matching technique. Using only the mode matching simulation of the original structure, the sensitivity of the scattering parameters is obtained. The adjoint network method (ANM) is applied to the generalized scattering matrices (GSMs) of …
