Metamaterial design for a metamaterial-enhanced resistive wall amplifier

Abstract

The metamaterial-enhanced resistive wall amplifier (ME-RWA) has been shown to theoretically have higher wideband gain than many commercially available high power microwave amplifiers. Previous work has idealized the situation by assuming the metamaterial of the structure to be a homogenous dielectric with a Drude dispersion model. This work investigates a practical meander line implementation of the metamaterial liner for the ME-RWA.
