Study of the Parameters Affecting Cylindrical Cloak Using Dispersive FDTD

In this paper, an ideal cylindrical metamaterial invisibility cloak with infinite-length which its electric permittivity and magnetic permeability mapped to the drude dispersion model is simulated. the sinusoidal plane waves with microwave frequencies used as sources. to this end, the dispersive finite-difference time-domain method (fdtd) used with convolutional perfectly matched layered (cpml) absorbing boundaries conditions. a comparison performed between scattering of cloaked and non-cloaked pec cylinder. and finally, the influence of incident wave frequency, thickness of cloak and observer angle relative to the propagation line to performance of cloak, was surveyed.
