| Abstract(in English) | Hybrid Trefftz finite element method (HTFEM) with a nonlinear eigenvalue problem solver, Sakurai-Sugiura projection method (SSM), for electromagnetic wave propagation problems is inspected for finding a procedure for discarding nonphysical solutions and dependence of computed eigenvalues on parameters of SSM. Numerical results of TE- and TM-wave propagation constants on a three-layer-dielectric slab waveguide and a slab waveguide with periodic thin conductor show that estimating value of condition numbers of HTFEM matrices at computed solutions or changing an integral path in SSM may point out nonphysical solutions. Moreover, the three-layer-dielectric slab waveguide's results show that propagation constants computed by SSM with proper parameters converge. |
