The scattering of perfectly conducting cylinder coated with non uniform plasma is studied in this paper, using a so called piecewise linear recursive convolution frequency dependent finite difference time domain (PLRC FD 2TD) method. By simulating the interaction of electromagnetic wave with unmagnetized plasma, some bistatic and wide band numerical results are obtained, which indicate that plasma cloaking can greatly reduce the back wave energy of radar targets.
