摘　　要：本文提出了一种构造全介质异向介质全新方法,根据Maxwell方程组及本构方程中传导电流与位移电流对于物质电/磁偶极短相同贡献,BST陶瓷中体位移电流取代金属中面传导电流,使BST陶瓷具有异向电磁特性.从理论和实验上证明了这一理论正确性.In this paper, we propose a novel approach to realize lefthanded metamaterials with pure dielectrics. Since conductive currents and displacement currents play the same roles in Maxwell＇s Equations to the electric or magnetic polarization in the constitutive relations, we propose the construction of lefthanded electromagnetic properties for BST ceramics using high dielectric resonators with a replacement of conductive current by displacement current. Computer simulation and experimental observation verify the validation of this theory.
