在短毫米波和亚毫米波段,圆型槽波导可望是一种有发展前途的传输线。本文结出了二级近似条件下圆型槽波导的特征方程及其解。解的结果与实验值相一致.
In short millimeter wave and sub-millimeter wave band, circular groove waveguide is expected to be a promising transmission line. In this paper, the characteristic equation of a circular groove waveguide under second-order approximation and its solution are given. The solution results are consistent with the experimental values.
