Abstract:
The objective of this research was to study and analyze of an electromagnetic wave of
inductive iris waveguide filter. The analysis method, based on Wave Iterative Method (WIM) was
used to calculate the amplitude of wave in the pixel and mode domains using Fast Fourier
Transform (FFT). The obtained results for the inductive iris waveguide filter presented scattering
parameters. We calculated the amplitude of waves and presented the electromagnetic field on the
iris waveguide filter circuits. These simulation results are good agreement with theoretically
analysis and another simulation program. Furthermore, the benefit of this method can reduce
computation time, suitable for designing of high frequency circuit, It can be applied for complex
waveguide circuits and used this for teaching aide in telecommunication domain.
