Numerical Treatment Of Microwave Guiding Problems Using The Interfered Waves Model (iwm)

摘要

This paper presents a two-dimensional frequency domain model for analyzing resonant structures. In this model, the transverse waves in the waveguide cross-section at any point are simulated by superposition of two waves in two perpendicular directions. The relationships between the physical wave parameters and the model parameters are derived. Results for cutoff wave numbers of homogeneous arbitrarily shaped cylindrical waveguides are given to test the validity of the model. These results are compared with available analytical solutions and results given by other published methods. The model proves to give good treatment for boundary conditions and accurate results with smaller matrix size in comparison with other numerical methods.
