Abstract

In this paper, the stability of the one dimensional (1D) finite-difference time-domain (FDTD) difference scheme for the high power microwave (HPM) atmosphere propagation model is analyzed. The derivation shows that the conventional Courant condition is still valid when the time step meets the constraint imposed by the collision frequency. Our conclusion confirms that the FDTD method is available in this case. This work provides a theoretical basis for the study of non-linear problems about HPM propagation in the atmosphere.
