Features Cascade Placements of Surface Gammadion Structures in Strip-Type Transmission Lines for Controlling Selective Properties

The results of electrodynamic modeling of the conducting properties of sections of strip-type microwave transmission lines containing surface gammadion configurations deposited on the back side of the conducting transmission line are obtained for one single-pass gammadion and a separately configured cascade of them, in comparison with the parameters of a conducting section with a two-pass gammadion. The studies have shown the possibilities of using and controlling the rejection-selective properties of such structures, as well as methods for adjusting the transmission coefficient S21 when cascading several gammadions. The results obtained may be of interest to developers of applied microwave range units.

针对单通伽马结构（single-pass gammadion）与独立配置的级联伽马结构，并与带有双通伽马结构（two-pass gammadion）的导电传输段参数进行对比，本研究完成了对沉积于导电传输线背面、带有表面伽马结构的带状微波传输线段导电特性的电磁建模，并得到了相应结果。研究表明，此类结构具备应用与调控其抑制选频特性的潜力，同时也揭示了级联多组伽马结构时调整传输系数S21的方法。本研究所得结果可供应用微波频段器件研发人员参考借鉴。
