This paper presents a study into the parameter‐retrieval methods of metasurfaces composed of isolated metallic unit‐cells. The classical method based on the effective‐medium theory is revisited by aiming at the point of effective thickness in use. The second method based on the generalized sheet transition conditions is also investigated and the extracted results are mutually verified with the classical method when the unity thickness is used. It is found that these two sets of effective parameters, surface susceptibilities and unity effective parameters, are mutually equivalent if they are not equal. The retrieved values are justified by those results available in literature.

在由孤立的金属单元构成的超表面的表面磁化率和有效参数上

本文提出了对由孤立的金属单元构成的超表面的参数检索方法的研究。针对有效介质理论，重新探讨了基于有效介质理论的经典方法。还研究了基于广义薄板转变条件的第二种方法，并且当使用单位厚度时，提取的结果与经典方法相互验证。发现这两组有效参数，即表面磁化率和统一有效参数，如果不相等则彼此相等。检索到的值由文献中提供的那些结果证明是正确的。
