 note = {application/pdf, A scheme based on the hybrid Trefftz finite element method (HTFEM) of electromagneticwave propagation in a waveguide results in a nonlinear eigenvalue problem. Solving theeigenvalue problem by the Sakurai-Sugiura projection method (SSM) yields all propagationconstants and spurious solutions in the region bounded with a closed integral pathfor SSM on the complex plane of the propagation constant. In our previous paper, usingdependency of the spurious solutions on the boundary of the region, we could discard thespurious solutions. Seeking a simple index which can separate the eigenvalues into thepropagation constants and spurious solutions, we examined following two values of thegeneralized eigenvalue problem with a Hankel and the shifted Hankel matrices computedby SSM: the sensitivity of the eigenvalue problem and the eigenvalue of the Hankel matrix.Numerical results of a three layered dielectric waveguide and a metallic grating on a slabwaveguide show the usefulness of the presented indices.},
