WIDE-BAND MODELING OF ARBITRARILY-SHAPED E-PLANE WAVE-GUIDE COMPONENTS BY THE BOUNDARY INTEGRAL-RESONANT MODE EXPANSION METHOD

The boundary integral-resonant mode expansion method is used for the s olution of the eigenvalue problem involved in the determination of the poles and the residues of the Y-parameters of arbitrarily shaped E-pl ane waveguide junctions, Using this method, the frequency response and its sensitivity to deformations of the boundary can be calculated muc h faster than by other more conventional methods for arbitrary shapes. Therefore, the described algorithm is eligible for setting up very ef ficient CAD tools to produce optimized designs of complex E-plane comp onents in reasonable times, Some examples demonstrate the efficiency o f the method in the modeling of components of practical interest.
