A new three-dimensional conical ground-plane cloak with homogeneous materials
A new three-dimensional conical ground-plane cloak with homogeneous materials
A new three dimensional conical ground plane electromag- netic cloak is proposed and designed based on the coordinate transfor- mation of Maxwell's equations. Material parameters of the conical invisible cloak are derived which have simple form and lesser inhomo- geneity compared with other 3-dimensional cloaks. Because of conve- nient form of the constitutive tensors of the conical cloak, we propose a new strategy for homogeneous approximation of the materials of the cloaks. Numerical simulations confirm that approximation with eight slices, is more than enough and this cloak can hide any object on the ground as well as inhomogeneous ones.

Abstract
A new three dimensional conical ground plane electromag- netic cloak is proposed and designed based on the coordinate transfor- mation of Maxwell's equations. Material parameters of the conical invisible cloak are derived which have simple form and lesser inhomo- geneity compared with other 3-dimensional cloaks. Because of conve- nient form of the constitutive tensors of the conical cloak, we propose a new strategy for homogeneous approximation of the materials of the cloaks. Numerical simulations confirm that approximation with eight slices, is more than enough and this cloak can hide any object on the ground as well as inhomogeneous ones.
