单色被动隐身衣性能的基本界限
Fundamental Bounds on the Performance of Monochromatic Passive Cloaks
摘要：
单色散射抵消和场归零斗篷的性能的基本界限，由预定义的线性被动材料占据一个预定义的设计区域，制定通过投影场量到一个子截面的基础上，并应用二次约束二次规划。配方的数值测试揭示了关键的物理趋势，以及两类斗篷之间的优点和缺点。结果表明，使用具有高介电对比度的低损耗材料提供了有效隐身的最高潜力。
英文摘要：
Fundamental bounds on the performance of monochromatic scattering-cancellation and field-zeroing cloaks made of prescribed linear passive materials occupying a predefined design region are formulated by projecting field quantities onto a sub-sectional basis and applying quadratically constrained quadratic programming. Formulations are numerically tested revealing key physical trends as well as advantages and disadvantages between the two classes of cloaks. Results show that the use of low-loss materials with high dielectric contrast affords the highest potential for effective cloaking.
