The contribution of higher-order spatial harmonics in eigenvalues and ohmic losses calculations in coaxial corrugated cavities

摘要

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.
