    • An insulated conducting wire (ICW) having an inorganic cladding and a microwire positioned within the cladding. The outer diameter of the microwire is less then the inner diameter of the cladding, and the insulated conducting wire is substantially free of bonding between the microwire and the cladding. A process of making a wire, having the steps of: drawing an inorganic tube through a heating zone such that the inner diameter of the tube is reduced; inserting a microwire into the tube whereby the tube becomes a cladding; and adjusting the draw process parameters such that the inner diameter of the cladding is larger than the outer diameter of the microwire, and the microwire and the cladding are not in contact with each other under thermal conditions that would cause bonding between the microwire and the cladding.
    • 一种绝缘导线(ICW),其具有无机包层和位于包层内的微线。 微丝的外径小于包层的内径,绝缘导线基本上没有微线与包层之间的结合。 一种制造线材的方法,具有以下步骤:通过加热区域拉伸无机管,使得管的内径减小; 将微丝插入管中,由此管变成包层; 并且调整拉伸工艺参数,使得包层的内径大于微丝的外径,并且在引起微丝和包层之间的结合的热条件下,微丝和包层彼此不接触 。

    • A lens system with a lens formed of a material having a negative index of refraction in an operational frequency range, a first surface of the material having a convex hyperbolic curvature, and a second surface of the material having a concave circular curvature. A lens system can include two of these lenses, arranged with the concave circular surfaces facing each other. Far field radiation arriving at the hyperbolic surface of the the first lens is refracted by the lens material toward the circular surface, out of the first lens in a direction parallel to the original radiation direction, and into the circular surface of the second lens, where it is refracted toward the hyperbolic surface of the second lens, and exits the second lens in a direction parallel to the original direction. The lens material can have a tunable or fixed negative refractive index and/or resonant frequency.
    • 一种透镜系统,其具有由在工作频率范围内具有负折射率的材料形成的透镜,所述材料的第一表面具有凸双曲线曲率,以及所述材料的第二表面具有凹的圆弧曲率。 透镜系统可以包括这些透镜中的两个,其中凹形圆形表面彼此面对。 到达第一透镜的双曲面的远场辐射被透镜材料朝平行于原始辐射方向的圆形表面折射出第一透镜,并进入第二透镜的圆形表面,其中 它朝向第二透镜的双曲面折射,并沿平行于原始方向的方向离开第二透镜。 透镜材料可以具有可调谐或固定的负折射率和/或谐振频率。
