RIGOROUS ANALYSIS OF E-PLANE T-JUNCTIONS IN RECTANGULAR WAVEGUIDES BY FOURIER TRANSFORM TECHNIQUE

摘要

A rigorous analysis for E-plane T-junctions in a rectangular waveguide is proposed by using normal Fourier transform technique. The coefficients of equations can be calculated by residue series and it is very fast convergent. Because of utilization of a more accuracy expression with respect to electromagnetic fields in the cavity region,and the matching planes become more less,as a result this method has the least unknown numbers in all of the methods reported,and so it is greatly advantageous to the design method. Another characteristic of the method is that Green function is not directly utilized and it is simply applicable to more complex construction.
