Inductive meandered line metamaterial for metamaterial-enhanced resistive wall amplifiers

The metamaterial-enhanced resistive wall amplifier (ME-RWA) has been demonstrated, through theory, to be a high gain wideband amplifier. This work presents the design and preliminary cold test results of a constructed ME-RWA. In this ME-RWA design, the metamaterial consists of a periodic arrangement of inductive meandered lines. To verify the properties of the metamaterial, the structure's dispersion was measured and found to be in good agreement with simulation and theory.
