Effects of high power on microwave metamaterials
In this paper we examine experimentally and numerically the effect of exposing a metamaterial to relatively high power EM waves. We show that a metamaterial consisting of a conventional Split Ring Resonator on an FR4 substrate can undergo combustion when exposed to 1W of RF. We compare the experimental results to numerical simulations, showing that numerical models can be accurately used to predict the thermal behaviour of metamaterials under exposure to high power RF.
