Advances on AMC for Transmission, Radiation, and Scattering

摘要: 介绍了人工磁导体用于波导传输、天线辐射和隐身材料的研究进展。通过金属导体和人工磁导体构造虚拟电/磁壁，设计了新型的平行板波导；利用人工磁导体作反射板，可实现低剖面天线系统的设计，并且通过改变极化依赖型人工地板上偶极子的取向，能够获得圆极化辐射特性；通过在人工磁导体上加载合适的电阻，可设计超薄的雷达吸波材料；利用人工磁导体反射相位特性，可设计低RCS的反射屏。

Abstract: This article introduces the advance on artificial magnetic conductor (AMC) for waveguide transmission, antenna radiation, and stealth materials. A new type of parallel plate waveguide is introduced which combines PEC parallel plates and AMC parallel plates for virtual electric/magnetic walls. The technical merits of this new waveguide are described in detail.
