a novel 3D finite-difference time-domain (FDTD) method
by which the electromagnetic scattering of the dispersive media can be analsized
is proposed.It is called the Current-Density-Laplace-Transfer FDTD (CLT-FDTD) algorithm.According to the constitutive relation equation between the current density vector and electric-field intensity
the constitutive relation of plasma medium is transformed to the s-domain by using the LT principle.Finally based on the inverse LT and the exponential time stepping
the FDTD iteration equations are obtained which is easy to be solved in the time domain. Using this method
the radar scattering cross-sections (RCS) of the non-magnetism and magnetization plasma ball are computed.The results show that this method is correct and efficient.
