Abstract

Based on compressing coordinate transformation (CCT) that transforms a region into a smaller region, a rigorous method for designing a cloak with controllable open window is proposed. The open cloak consists of a portion of an ideal closed cloak and an independent system whose position and parameters can be controlled. The system could be circular or diamond-shaped with coordinate transformation in radius direction and one axis of Cartesian coordinates, respectively. This cloak is able to externally hide an arbitrary-shaped object with arbitrary material property including PEC, and the object is open to the outside space. Full-wave simulations validate this rigorous cloaking concept.
