摘要
From the staggered field components provided by the finite-difference time-domain (FDTD) method, we use interpolation to obtain six field components at the same location and at the same time instant in order to calculate the power density, (PD) of the electromagnetic field (EMF). The subvoxel modeling of the scattering object is also discussed. Comparisons indicate that the joint application of the interpolation and the subvoxel modeling effectively improves the PD precision and significantly reduces the computer memory required to implement the FDTD method.
