摘 要：
本文基于功率流分别讨论了在矩形波导横截面积一定,TE_(m0)和TM_(mn)模式单独传输时,宽长尺寸比的最优解问题,得到了TE_(m0)波传播时,其宽长比应趋近于0;TM_(mm)波传播时,m
Based on the research of power flow in the rectangular wavegnide which cross - sectional area is a constant, the optimal solution about the width to length ration of rectangular waveguide is discussed. While wave propagation of TEm0 and TMm, in rectangular waveguide respectively,the aspect ratio of TEm0 wave propagating should be closed to zero. When the TMmn wave propagating, m 〈 n and the width length ratio of TM12 is one; but m≥n, the width to lenth ratio is n/m. The results have the potential applications in the rectangular waveguide size selection and design.
