Abstract：A fast solution to the Volume Integral Equation (VIE) for 3-D dielectric objects is implemented by using the precorrected-FFT method. A new stencil topology is presented to reduce near-zone interactions to be computed directly and precorrected, in which the projection and interpolation stencils are floating but not fixed. Numerical results show that the P-FFT method based on floating stencil can significantly reduce near-zone interactions to be precorrected, as well as memory and CPU time.
