MRTD analysis of a transient electromagnetic pulse propagating through a dielectric layer

On the basis of a scaling function based multiresolution time domain (MRTD) scheme, we analyse a transient electromagnetic pulse propagating through a dielectric layer in conjunction with an anisotropic perfectly matched laye r (APML) for mesh truncation. Herein we have carefully investigated three d ifferent cases including TEMx, TEz and TMz waves that are normally incident on an open or PEC parallel-plate bounded propagation system. Purposely. we employ a similar notation in formulations to that applied in the conventio nal finite difference time-domain (FDTD) method for their comparison, rathe r than using the state-space representation. It is found that the computed reflected coefficients for all configurations are in good agreement with th ose obtained with the FDTD and analytic methods, while its corresponding re quirement on computational memory and CPU time is considerably reduced.
