运用双层周期性电路结构实现凋落波放大的精确设计
Exact Design of Evanescent-Wave Amplication Using Bilayer Periodic Circuit Structures
本文提出了一种有效的分析方法以用于凋落波放大的精确设计，其中的周期性排列串并联电容可等效为磁等离子体层而周期性排列的串并联电感则等效为电等离子体层。在精确提取结构中各寄生电路参数的基础上，即可完成任意所需频率点上的凋落波放大。 全波仿真结果显示基于本方法所设计的凋落波放大其频偏误差小于0.1%，而最终的实验测试结果跟仿真结果也非常的吻合。 本文所提供的有效分析方法也可应用于其他周期性电路结构分析中，而精确的凋落波放大也为其实际应用提供了可能。
n efficient method is presented to design the evanescent wave amplification exactly by cascading two layers of periodic series-shunt capacitors and and inductors, which simulate a bilayer of magnetic and electric plasmas. Based on the presented method, equivalent lumped parameters of circuit structures are retrieved, from which the evanescent-wave amplification (EWA) is obtained at a designed frequency. Full-wave simulations show that the relative offset of the EWA frequency is less than 0.1%. The structure has been fabricated and measured, and the measurement results have good agreements with the simulation results. The proposed method can be used to design other periodic circuit structures, and the exact design of EWA can be used in the fabrication of novel components.
