摘要
给出了H_(01)模圆波导阶梯等效导纳的变分解。计算了K_a波段阶梯导纳的频响特性。结果表明,H_(01)模圆波导阶梯的等效导纳和反射系数将随工作频率的升高而减小.
A solution of the equivalent admittance on the cylindrical waveguide step operating H01 mode is derived by variational method. As an example the frequency response of the step ad-mittance is computed in the Ka band. The results show that the admittance and the reflection coefficient of the waveguide step decrease with the increase of frequency.
