我们已经设计，生产，并实验表征2.7毫米厚的复合面板havingnegative折射率在8.4和9.2 GHz之间。复合超材料是使用传统的商业多层电路板光刻技术制造的;通过使用通孔来形成垂直于电路板表面方向上的散射元件部分，引入三维物理（与电磁相反）结构。从散射参数的测量，我们表明，复杂的介电常数，磁导率，指数，和阻抗的复合材料可以明确地确定。该方法能够定量确定负折射率带和相关损失。DOI：10.1103/PhysRevB.70.113102 PACS编号：42.25.Bs，41.20.Jb，73.20.Mf
We have designed, produced, and experimentally characterized 2.7 mm thick composite panels havingnegative refractive index between 8.4 and 9.2 GHz. The composite metamaterial is fabricated using conven-tional commercial multilayer circuit-board lithography; three-dimensional physical(as opposed to electromag-netic) structure is introduced by the use of vias to form sections of the scattering elements in the directionperpendicular to the circuit board surfaces. From scattering parameter measurements, we show that the com-plex permittivity, permeability, index, and impedance of the composite can be unambiguously determined. Themeasurements enable the quantitative determination of the negative index band and associated losses. Theextracted material parameters are shown to be in excellent agreement with simulation results.DOI: 10.1103/PhysRevB.70.113102 PACS number(s): 42.25.Bs, 41.20.Jb, 73.20.Mf
