A compact high-power microwave metamaterial slow-wave structure: From computational design to hot test validation

There is considerable interest in exploiting metamaterials to engineer dispersion relations for new beam/wave interactions that are not possible using conventional all-metal periodic structures. In this paper, we describe the computational design, and both calculated and experimental cold and hot tests of a new high-power microwave slow wave structure at the University of New Mexico to generate a record 100 MW of power in L-band in a very compact size.
