A plasma metamaterial is a composite of plasma and solid metamaterials exhibiting various extraordinary features in contrast to typical microwave media. One of the advantages in plasma metamaterials is tunability in their internal parameters, and for regulation of microwaves paths, spatial gradients of electron density and permittivity also play significant roles. So far, microwave detouring or cloaking was achieved using solid state metamaterials. In contrast, we have reported that, due to these gradients, compactness of the detouring layer is possible, which is a good technological merit. In this study, we show experimental results on flattened propagation of microwaves with reduced wave scattering.
