摘要

本文对一种可切换平行板波导进行了参数化研究，该波导由基于超材料的高阻抗微带表面、金属平面和中间填充的介电层组成。表面的几何形状可以通过直接偏置穿过两个金属平面的二极管来切换，而无需使用任何进一步的专用网络。电磁模拟中考虑了几何参数和材料参数的变化。通过色散图的方法报道了为滤波应用而设计的具有几个电磁带隙的拟议结构的频率行为。大量的带隙及其变化使得该结构适用于高灵敏度传感器或具有高陡滚降的滤波器。

Characteristics of a switchable metamaterial based parallel plate waveguide derived by electromagnetic simulation

A parametric study of a switchable parallel-plate waveguide, consisting of a metamaterial based high impedance surface built in microstrip technology, a metal plane and a dielectric layer filling the space between them is presented. The geometry of the surface can be switched by means of diodes directly biased through the two metallic planes without employing any further dedicated network. Variations of both geometrical and material parameters have been considered in the electromagnetic simulations. The frequency behavior of the proposed structures, devised for filtering applications and featuring several electromagnetic band-gaps is reported by means of dispersion diagrams. The large number of band-gaps and their variation makes the structure suitable for high sensitivity sensors or filters with high steep roll-off.
