Abstract :
Higher-order finite difference time domain techniques make use of additional samples on the Yee grid in order to reduce the anisotropy, phase error and dispersion of the standard technique. The authors describe the implementation and verification of the perfectly matched layer (PML) absorbing boundary condition for the (2:4) technique
