Perturbation analysis is applied to calculate the radiation loss from corrugated waveguides for TM polarized guided waves. It is shown that the radiated power is strongly dependent upon radiation angle. A significant drop in output radiation occurs for radiation normal to the waveguide. Numerical results for waveguide structures having rectangular and sinusoidal corrugation profiles are included.
