论文摘要
披肩通常是倒数的。我们在这里介绍了\ emph {可传输的非倒数披肩}的概念,在该概念中,覆盖系统作为外部照明的标准杂志斗篷运行,但可以随意从其中心向外传输光线。我们证明了这种披肩的特定实现,该实现是由一组同心的双性异性跨面组成的,其最内向的元素是非偏置的,并且设计用于同时阻止内向波和通过 - 不全面或方向性地传递 - 向外波 - 向外波。这种披肩代表了传统披风的基本多样性,并可能在隐身,避免阻塞,幻觉和冷却等领域中找到应用。
Cloaking is typically reciprocal. We introduce here the concept of \emph{transmittable nonreciprocal cloaking} whereby the cloaking system operates as a standard omnidirectional cloak for external illumination, but can transmit light from its center outwards at will. We demonstrate a specific implementation of such cloaking that consists in a set of concentric bianisotropic metasurfaces whose innermost element is nonreciprocal and designed to simultaneously block inward waves and pass -- either omnidirectionaly or directionally -- outward waves. Such cloaking represents a fundamental diversification of conventional cloaking and may find applications in areas such as stealth, blockage avoidance, illusion and cooling.
