FDTD implementation for magnetoplasma medium using exponential time differencing

The electromagnetic propagation in dispersive magnetoplasma medium is modeled using the finite-difference time-domain (FDTD) method based on the exponential time differencing (ETD). The ETD schemes with first-order and second-order accuracy are presented. The ETD algorithm is accurate and efficient. The reflection and transmission coefficients of the magnetized slab for the right-hand circularly polarized wave are computed.
