a metasurface having a plurality of resonators, wherein the metasurface includes a conformal substrate that is conformable to a curvilinear surface and supporting the plurality of resonators, wherein the metasurface has an area, wherein the plurality of resonators support plasmonic transfer of incident radiation across the surface, and wherein the metasurface provides a radar cross section that is larger than a radar cross section of the area of substrate itself without the plurality of resonators;
wherein the conformable substrate is disposed on a vehicle.
