Abstract :
The propagation constants of Floquet modes in corrugated circular waveguides with continuous corrugation profiles were determined from a formulation leading to a canonical matrix eigenvalue equation. The approach is validated by comparison to available data for the dispersion relation of TM/sub 0(n)/ modes in a sinusoidally corrugated waveguide. Results for hybrid modes were also presented.
