Abstract
In this paper, a wedge-shaped invisibility cloak whose diameter gradually increases along the arms of the wedge
is introduced. The constitutive parameters of the cloak are obtained using a proper transformation. By considering two
special cases for incident fields, (TEz and TMz), and paying attention that the wedge structure is invariant in axial and
radial directions, the reduced set of cloaking parameters are obtained spatially invariant and larger than one, keeping
the PML (perfectly matched layer) condition for perfect cloaking performance. Spatially invariant and isotropic
constitutive parameters lead to the physically realizable cloak in a wide band of frequency for this specific type of
incident fields.
