Abstract
Introduction. Algorithm for solving eigenvalue problem of open inhomogeneous dielectric waveguide is presented. Open waveguide divided into two regions. Inner inhomogeneous region is discretized using node–edge finite elements. Fields in outer unbounded homogeneous region expanded into cylindrical harmonics. The final nonlinear eigenvalue problem is solved using inverse iteration procedure. Results. Calculated surface waves of circular inhomogeneous object. Literature overview on the excitation of open waveguide is presented. Conclusions. Above algorithm allow to determine the discrete spectrum of waves in open inhomogeneous waveguide
