The development of Fast Modal Fourier Transform for electromagnetic wave iterative computation

Abstract

In this paper, we explain the Fast Modal Fourier transform (FMFT) based on wave iterative method, which apply to electromagnetic wave computation. The FMFT developed on GUI function of MATLAB software, computes the electromagnetic waves of spectrum domain (mode) including incident wave, reflected wave and transmitted wave to propagate in waveguide (Aluminums materials). Various combinations of mathematical model have been analyzed to describe system characteristics. The performances of the FMFT based on Wave Iterative Computation (WIC) are illustrated using a waveguide iris filter. It can be seen that computed results were successfully in comparing with classical methods.
