Abstract

The approach of designing cloaks with arbitrary shapes was investigated. The coordinate transformation was considered as a homeomorphous topological mapping and the related geometrical description was proposed by introducing position surfaces and tracing lines. Then an approximation approach was presented, which considers a close shape as a polyhedron and performs the spatial compression in a general method. As an example of this approach, we deduced the material parameter equations for two-dimensional polygon cloaks and confirmed the results through numerical simulations. Our approach opens up possibilities of designing practical cloaks with arbitrary shapes through numerical or/and semi-analytical methods.

Fig. 1.

(Color online) Sketches of PSs (or PCs in 2D spaces, solid lines) and TLs (dashed lines): (a) for very complicated shapes and in general, the TLs may be curve, straight or alternately curve and straight; (b) in the simple cases, inside a cloak volume, as long as there is one inner point from which all the points on the cloak surface can be reached along straight lines, such cloaks have straight TLs.

Fig. 2.
Fig. 2.

(Color online) Sketches of PSs (or PCs in 2D spaces, solid lines) and TLs (dashed lines) when polyhedron (or polygon in 2D spaces) approximations are made. Compared with the shapes (sketched by dotted lines here) shown in Fig. 1, the PSs are constructed by planes (or straight lines in 2D spaces) and, in some regions, the TLs can be simplified as straight lines.

(Color online) The electric-field distributions when electromagnetic waves are put on the cloak (a) horizontally and (b) perpendicularly.
