Electrodynamic characteristics of a straight strip antenna located at a plane interface of a uniaxial metamaterial and an isotropic magnetodielectric are studied using the integral equation method. The antenna is perpendicular to the anisotropy axis of the metamaterial filling the half-space on one side of the interface and is excited by a given voltage. The cases of metamaterials with hyperbolic and nonhyperbolic dispersion are considered. A closed-form solution for the current distribution of an infinitely long strip is obtained and the input impedance of such an antenna is found. Based on this solution, the limits of applicability of the transmission line theory for determining the characteristics of the antenna are established and a generalization to the case of a finite-length strip antenna is discussed.

位于单轴超材料和各向同性磁电介质平面界面的条形天线理论

采用积分方程法研究了位于单轴超材料和各向同性磁电介质平面界面的直条天线的电动力学特性。天线垂直于填充界面一侧半空间的超材料的各向异性轴，并由给定电压激发。考虑了具有双曲和非双曲色散的超材料的情况。获得了无限长条带电流分布的封闭形式解，并找到了这种天线的输入阻抗。在此解决方案的基础上，确定了传输线理论在确定天线特性方面的适用性限制，并讨论了对有限长度带状天线情况的推广。
