Study on EM pulse radiation problems with time domain MEI method

The electromagnetic pulse radiation problem is the starting point for high power microwaves radiation, propagation and scattering. This paper applies the finite difference time domain technique(FDTD) combined with the timedomain measured equation of invariance method(MEI) to calculate line source radiation problem with near truncating boundary. The numerical results show that MEI boundary condition has high effect and high accuracy than two-order Mur boundary condition.
