Abstract :
A boundary integral formulation for quasistatic, transverse electric, transverse magnetic, and hybrid wave analysis of open or shielded waveguides with arbitrary multiregion cross section is presented. A special form of boundary integral equation is derived to make possible the numerical treatment of cornered geometries. Subsequently, operator equations including source terms are given for the analysis of arbitrary two-dimensional structures. The numerical method is described briefly, with the quasistatic analysis of a coplanar waveguide with a nonrectangular conductor shape considered as an example.<>
