Abstract
This article presents the results of numerical simulation and optimization of electromagnetic characteristics of a new waveguide polarizer design containing a conducting diaphragm and pins. The theoretical model of a waveguide polarizer with one diaphragm and four pins is developed and applied for the optimization. The main electromagnetic characteristics of the polarizer were obtained based on the elements of general scattering matrix of the designed device. In order to check the performance of the developed mathematical model it was simulated in a software using the finite difference time domain (FDTD) technique. The proposed design of a waveguide polarizer has the ability of fine tuning of its characteristics by mechanical change of the heights of applied pins. Developed theoretical approach and obtained numerical results can be used to develop new tunable waveguide polarizers and filters with diaphragms and pins.
