开发了一种方法来计算波纹金属表面的微波反射以及预期的欧姆损耗和相移。所实施的 FDTD 算法将壁视为截止频率远高于微波频率的等离子体。这会产生电流与 E/M 场的自洽解。描述算法后，显示了与损耗和相位测量的比较，并建议了优化的波纹轮廓。
A method was developed to calculate the reflection of microwaves at corrugated metallic surfaces along with the expected ohmic losses and phase shifts. The implemented FDTD algorithm treats the wall as a plasma with a cutoff frequency far above the microwave frequency. This results in a self-consistent solution of the currents together with the E/M fields. After describing the algorithm, comparisons with loss and phase measurements are shown and an optimized corrugation profile is suggested.
