Electromagnetic Wave Interactions with a Metamaterial Cloak [PDF]

open access: yesPhysical Review Letters, 2007
We establish analytically the interactions of electromagnetic wave with a general class of spherical cloaks based on a full wave Mie scattering model. We show that for an ideal cloak the total scattering cross section is absolutely zero, but for a cloak with a specific type of loss, only the backscattering is exactly zero, which indicates the cloak can
