Analysis of Absorbing Characteristics of One-Layer EM-Absorber Using CIP Method

摘要

In this paper, Constrained Interpolation Profile (CIP) method is applied to Maxwell's equation including complex permittivity and permeability and the validity of CIP method applied to the equation is confirmed compared with the FDTD method. And the dependency on CFL (Courant-Friedrich-Lewy) condition, cell size and estimates of partial deriv ε/partial deriv x, partial deriv μ/partial deriv x and partial deriv σ/partial deriv x of the absorbing characteristics of one-layer EM-absorber are calculated using CIP method and compared with that by FDTD method. As a result, it is confirmed that the characteristics obtained by CIP method is different from that by FDTD method.
