Negatively-refractive focusing and sensing apparatus, methods, and systems
摘要：
Apparatus, methods, and systems provide negatively-refractive focusing and sensing of electromagnetic energy. In some approaches the negatively-refractive focusing includes providing an interior focusing region with an axial magnification substantially less than one. In some approaches the negatively-refractive focusing includes negatively-refractive focusing with a transformation medium, where the transformation medium may include an artificially-structured material such as a metamaterial.
摘要（中）：

装置，方法和系统提供负折射聚焦和电磁能的感测。 在一些方法中，负折射聚焦包括提供具有基本上小于1的轴向倍率的内部聚焦区域。 在一些方法中，负折射聚焦包括与转化介质的负折射聚焦，其中转化介质可以包括人造结构的材料，例如超材料。
