To support exploration of the effects of electromagnetic waves produced by a transient pulse, AltaSim Technologies has developed computational approaches for treating the transient nature of a pulse with asymmetric, non-zero-rise and decay times. The shape of the current pulse applied to the electric dipole was represented by a heavy-side exponential function with independent, non-zero rise and decay times. The current pulse was integrated into COMSOL Multiphysics to provide solutions for the electric and magnetic response of an electric dipole.
