Abstract :
A carpet cloak of invisibility for sinusoidal periodic boundaries to mimic a specular flat floor is introduced. The material parameters are derived based on a non-conformal coordinate transformation, and a carpet cloak is designed and implemented based on the transmission line metamaterials concept with an equivalent circuit model. Wideband specular reflection operations of the carpet cloak are confirmed by circuit simulations.
