Abstract

This paper addresses guided wave propagation in threedimensional open omega waveguides. The analysis uses a mode matching technique, is focused on the discrete modes and includes both guidance and leakage behavior. It is shown that, in some ranges of operation, the discrete surface modes turn into leaky modes due to TE-TM mode coupling, an effect already known for isotropic dielectric waveguides. The numerical results show the influence of the medium and geometrical parameters on the attenuation and phase constants of these leaky modes.
