本文根据耦合波理论,应用计算机对H(?)波扇形变换器进行了分析,给出了适用于任何波段的C_j(p_i)(j=1,2,3;i=1,2)和C_K~(?)(p_i)(K=1,2;i=1,2)曲线,以及其它一些对设计H(?)波扇形变换器有实用意义的结果.作为例子,在8mm 波段计算了不同(?)a 值,不同频率下各杂波引起的变换损耗和它们与(?)波之间的耦合系数.计算结果表明:E_(12),H_(12),E_(11)和H_(22)波变换损耗之和占总变换损耗的82%其中又以E_(12)波最为突出约占总损耗的1/3.据此,文中初步探封了改善扇形变换器输出圆电波纯度的可能途径.
According to the coupled wave theory, the H (?) Wave fan converter is analyzed by computer and the C_j (p_i) (j = 1,2,3; i = 1,2) and C_K ~ (?) (p_i) (K = 1,2; i = 1,2) curves, and other practical results for designing a H (?) wave sector converter. As an example, (?) a, transformation loss caused by each clutter at different frequencies and the coupling coefficient between them and (?) wave.The calculated results show that E12, H12, E11 and H_ 22) The sum of the wave transformation loss accounts for 82% of the total transformation loss, of which the E (12) wave is the most prominent, accounting for about one-third of the total loss.Therefore, the paper preliminarily probes the problem of improving the output radio wave purity of the fan- Possible way.
