The properties of two-dimensional electromagnetic cloaks which are devoid of rotational symmetry have been investigated by considering an eccentric elliptic annular cloak. The validity of the design was confirmed by full-wave simulations of plane wave scattering by a PEC cylinder with and without the cloak. The design example presented in this paper represents an important generalization of conventional concentric annular cloak designs toward the design of arbitrarily shaped and unsymmetrical electromagnetic cloaks.
