复合薄膜中的可控相干完全吸收
Controllable coherent perfect absorption in a composite film
摘要：
我们利用金属-介电复合材料提供的多功能性，以证明在一个板的非均匀介质中的可控相干完美吸收（CPA）。板从两侧的相干光照射，在相同的入射角和CPA所需的条件进行了调查作为不同的几何参数的函数。同时实现的CPA在两个不同的频率也示出。最后，我们的计算清楚地阐明了作为CPA的必要先决条件的吸收的作用。
英文摘要：
We exploit the versatility provided by metal--dielectric composites to demonstrate controllable coherent perfect absorption (CPA) in a slab of heterogeneous medium. The slab is illuminated by coherent light from both sides, at the same angle of incidence and the conditions required for CPA are investigated as a function of the different geometrical parameters. The simultaneous realization of CPA at two distinct frequencies is also shown. Finally, our calculations clearly elucidate the role of absorption as a necessary prerequisite for CPA.
