近年来对波纹波导的研究一直很感兴趣,圆形,矩形和椭圆形波纹波导的传播特性已有许多人作了研究。适当构成所需尺寸可使内壁损耗衰减很小,因而在低损耗波导传输系统的应用中则变得引人注目。圆形波纹波导在用最低次混合模激励时能够维持均匀横向分布的场,这种特性对设计抛物面反射器天线的高效 In recent years, research on waveguided waveguide has been very much interested. The propagation characteristics of circular, rectangular and elliptical waveguides have been studied by many people. Properly sized to minimize wall losses, it becomes noticeable in low loss waveguide applications. Circular corrugated waveguides are capable of maintaining an even and laterally distributed field when excited with the lowest mixing mode, a feature that is highly efficient at designing parabolic reflector antennas
