The Development of Simulation Tools for Design of Waveguide Filter using Resonant Iris Circuit

摘要

This paper presents a development of Electromagnetic simulation tool for design of rectangular waveguide filter using inductive-capacitive resonant iris circuit.The simulation is designed and developed by using the electromagnetic wave propagation and iterative method to calculate the amplitude of waves in the frequency and spatial domain.The developed EM simulation,called WCD (Waveguide Circuit Design) consists of menu,designed,calculating and displayed windows which were designed by using GUI (Graphic User Interface) of MATLAB(R)software.In this paper,the resonant iris circuit in the waveguide are simulated and compared to the CST Microwave Studio(R).The simulated results present correctly the circuit properties and electric and current distribution on the waveguide iris circuit.The results agree with theory,CST simulation.
