he piecewise linear recursive convolution(PLRC)is proposed for cold plasma medium using finite-difference time-domain(FDTD) method.In PLRC algorithm,the electric field with time is piecewise interpolated and the recursive convolution was introduced.The reflection and transmission coefficients were calculated by the electromagnetic response of a differential Gaussian pulse.The calculation results are validated with analytic values and the results agree well with each other.The calculation results show that higher frequency microwave can transmit through the plasma and lower frequency is forbidden.
