| Abstract: | The Lunar waveguides and vained circular waveguides are analyzed by using the mode matching method. The fields in the waveguides are expressed by cylindrical harmonic expansions in which Bessel functions with half orders are involved and the boundary conditions are imposed. Characteristic equations for cutoff wave numbers for both TE and TM modes are obtained. Several waveguides of different relative dimension are calculated, and the results show high accuracy and are considerably steady. |
