Abstract :
The Spatial Harmonics Method has been used to study TE modes in a coaxial corrugated cavity. A numerical code has been developed to calculate eigenvalues, fields and ohmic losses on the walls. Numerical results are presented to clarify the influence of the higher-order spatial harmonics to these calculations.
