A concept for cloaking using electrically-thin dielectric surfaces

An electrically thin cloaking device in the form of a tile is proposed here. Based on the phase velocity the wave direction of the reflected fields are steered with a designed angle. An electrically large object may be cloaked by using one or multiple tiles. Each tile is made of concentric annular s...

Summary:An electrically thin cloaking device in the form of a tile is proposed here. Based on the phase velocity the wave direction of the reflected fields are steered with a designed angle. An electrically large object may be cloaked by using one or multiple tiles. Each tile is made of concentric annular squared rings that tailor the phase velocity of the wave within the device, such that the reflected wave is redirected to the desired orientation. A numerical simulation is presented here as a validation of the design and concept. The monostatic radar cross section is significantly reduced.
