Abstract :
A time integration scheme is presented to simulate electromagnetic wave propagation in a ferrite medium. A stable, non-dissipative, second-order scheme is achieved using both central differences and averages by considering the torque equation of motion for electron precession in conjunction with Maxwell´s equations. Also presented is an error analysis which accounts for an electromagnetic wave propagating in an unbounded numerical ferrite grid that is homogeneous and fully saturated. The approach is validated using a shorted stripline with ferrite loading.
