%X The foundational principle of the nonorthogonal PD-TD algorithm is introduced, and its stability condition and dispersion equation are derived. The numerical dispersion characteristics of this method are analyzed in detail. In order to show its validity the scattering surface currents of perfectly conducting cylinder are calculated by using this method when the incident wave is sinusoidal plane wave in TM case. The numerical results agree with that by moment method very well. Then the TM scattering problem of polygon cylinder coated with absorbing material is studied and the monostatic RCS of the target is obtained. For comparison with results of equivalent source method the electric scattering distribution pattern of square cylinder coated with absorbing material is also obtained by using nonorthogonal FD-TD.
