Adaptive Time Stepping for Electromagnetic Models With Sinusoidal Dynamics

The numerical integration of electromagnetic models with sinusoidal excitation should be implemented in a special manner because standard adaptive Runge-Kutta integration methods do not work properly if the difference between the main and the embedded order of approximations is one. In this paper, a new class of adaptive time stepping schemes specially designed for the numerical integration of the electromagnetic models with sinusoidal dynamics is proposed.
