Plasma Metamaterials for Arbitrary Complex-Amplitude Wave Filters

摘要

In this project, we investigated arbitrary complex functions for electromagnetic waves by using a plasma array reinforced by metallic components and changing a pattern of series switches, external power for plasma generation, and pressure of discharge gases. In Section II., we describe the theoretical part of this project, where plasma metamaterials were predicted for the purpose of potential complex wave filters for the first time. In Section III, we show the experimental part of this project, and verified flexible complex function filters composed of plasma metamaterials, using newly-developed microwave analytical circuit.
