Abstract(in English) | The condition to reduce the measurement error is not quite clear for the reflectivity measurement of EM-wave absorbers by free space method. Therefore, we developed the numerical analysis method by combining the scattered field representation FDTD and the equivalence theorem. The dipole source is introduced to assume the spherical wave for the incident wave. A λ/4-type wave absorber model is introduced and the reflectivity error is numerically demonstrated in some cases. Besides, the qualitative discussion is given on the meaning of fulfilling the far-field condition and ensuring the first Fresnel zone. |
