Title: Electromagnetic wave interactions with a metamaterial cloak
Author: Chen, Hongsheng; Wu, Bae-Ian; Zhang, Baile; Kong, Jin Au

Abstract: 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 still be rendered invisible with a monostatic (transmitter and receiver in the same location) detection. Furthermore, we show that for a cloak with imperfect parameters the bistatic (transmitter and receiver in different locations) scattering performance is more sensitive to ηt=√μt/ϵt than nt=√μtϵt.
