X波段新型电磁隐身媒质的仿真研究

ccording to J.B.Pendry's cloaking theory, we design two cloaking models, a single cylindrical shell and double ones. Because of the specific transformation of the permittivity and permeability of the shell, the electromagnetic waves are bent smoothly inside the cloaking material and keep the original transmitting direction when they get out of the shell. The interior field can be excluded from a penetrable object without perturbing the exterior fields and the scattering is minimal in any direction. The electromagnetic simulations in X-band were performed to verify these ideal cloaking properties of the electromagnetic material.
