金属包复四层波导结构中的长程表面模
Long-range surface modes of metal-clad four-Layer waveguides
摘要
本文从理论上研究了金属包复四层波导中的表面模,指出可以在其中激发长程表面模.用角度扫描衰减全反射方法研究了这种波导中的长程表面模,测量了其传播常数和损耗与波导参数的关系.实验结果和理论计算相符.
Abstract
The surface modes of metal-clad four-layer waveguides were analysed theoretically. We found that the long-range surface modes could be excited in such waveguides. The long-range surface modes were studied experimentally by using the angle-scanning-attenuated total-reflection method, the dependence of wave vector mode losses on waveguide parameters was measured. Experimental results were in good agreement with theoretical calculations.
