摘要

研究了一种描述由亚波长大小的电容加载条状内含物组成的超材料吸收体在接地介质衬底上对具有一般入射方向和偏振方向的平面波的镜面反射的阻抗方法。研究了将吸收体模拟为具有有效表面阻抗的阻抗边界的可能性，并提出了一种由法向反射系数确定斜入射处镜面反射系数的简单方法。

An impedance formulation to determine specular reflection from metamaterial absorbers composed of capacitively loaded strip inclusions

An impedance approach to describe specular reflection of plane waves with general direction of incidence and polarization from metamaterial absorbers composed of a metasurface of sub-wavelength sized capacitively loaded strip inclusions on a grounded dielectric substrate is studied. The possibility to model the absorber as an impedance boundary with an effective surface impedance is examined and a simple method to determine the specular reflection coefficient at oblique incidence from the normal incidence reflection coefficient is proposed.
