Wideband RCS Reduction by Single-Layer Phase Gradient Modulated Surface.

This paper deals with the design and fabrication of an unpretentious (single-layer, without any lump element) broadband (97%, 11.3-32.3 GHz) radar cross-section reduction (RCSR) modulated surface (MS).

Effect of optical transformation order on design of arbitrary polygonal invisible cloak.

The design of an arbitrary polygonal invisible cloak is introduced in this paper by considering the different transformation orders. The transformation order is considered as a design variable to achieve the allowable constitutive parameters for a practical cloak with the optimum performance. In the proposed method, a thin layer is removed from the inner cloak boundary to avoid the inevitable singularity at this boundary.

Arbitrary n-sided irregular polygonal electromagnetic transformed media.

The design of an arbitrary n-sided irregular polygonal transformed media is introduced in this paper. The generalized proposed optical transformation is based on a very simple Y-intercept transformation in the Cartesian coordinate system. In this method, the arbitrary shaped transformed media is decomposed into triangular segments.
