Abstract

We present electromagnetic invisible cloaks and concentrators whichare composed of inhomogeneous and anisotropic metamaterials with asquare-shaped outer boundary and a circular-shaped inner boundary.Using the technique of coordinate transformation, closed-formformulations of the permittivity and permeability tensors have beenderived for the metamaterials to realize the invisible cloaking andto concentrate electromagnetic waves. Full-wave simulation resultsare given to validate the non-rotationally invariant cloaks andconcentrators.
