摘　　要：本文提出了工作在X波段的单面双S型异向介质结构,在仿真、实验两个方面对这种新型异向介质的异向特性进行了验证.实验和仿真结果均表明,这种新型的异向介质结构在这一工作频率下具有负折射特性.这种新型的异向介质具有两个优势:更加便于制造和便于添加可控器件使单面异向介质成为可控异向介质.The paper presents a single-sided double-S left-handed metamaterial structure in the X-band.The left-handed property of the new metamaterial has been verified by numerical simulation and experiment.Experimental results show the existence of the negative refraction within the same frequency band as indicated by the simulation.The proposed structure makes it easy to fabricate and feasible to make controllable metamaterial by incorporating itself with controllable elements.
