PARAMETER DESIGN OF INVISIBLE ANTI-CLOAK BASED ON NONLINEAR TRANSFORMATION

By Z. Han and Y.-L. Zhang

Full Article PDF (437 KB)

Abstract:
In this paper, we propose a new methodology to design an electromagnetic invisibility anti-cloak, which is based on nonlinear coordinate transformation. Cylindrical and elliptical shapes are presented to show the validation of the proposed methodology. We verify and analyze the above model with nonlinear transformation respectively. Full-wave simulations are given to illustrate the ability of the nonlinear transformation, which is advantageous for reducing the design difficulty of the anti-cloak. And the cloak shielding is broken, and the electromagnetic waves can go through the cloak. It is of particular importance in microwave communication applications.
