Finite element analysis of rectangular waveguide with inclined corners

摘要

Rectangular waveguide with inclined corners is analyzed using finite element method (FEM). The effect of inclination of two, three and four corners on bandwidth and cut-off frequency for TE_(10) and TE_(20) modes is studied. The variations in bandwidth and cut-off frequency for TE_(10) and TE_(20) modes are also observed. The bandwidth and cut-off frequencies are found to be increased as compared to those of normal rectangular waveguide.
