摘要:
本文研究了等离子体结构中耗散为热量的时间平均电磁功率的爆增方式与反常局域共振之间可能存在的关联。我们证明,在一种设定下,只要发生共振就会出现局域共振,且功率始终有界并可能趋于0。我们还给出了另一种设定:其中共振是完全的,只要发生共振功率就会趋于无穷大;由此可知该设定下不存在局域共振。本研究的动机来自近期关于通过反常局域共振实现隐身的工作。
英文摘要:
This paper studies a possible connection between the way the time averaged electromagnetic power dissipated into heat blows up and the anomalous localized resonance in plasmonic structures. We show that there is a setting in which the localized resonance takes place whenever the resonance does and moreover, the power is always bounded and might go to $0$. We also provide another setting in which the resonance is complete and the power goes to infinity whenever resonance occurs; as a consequence of this fact there is no localized resonance. This work is motivated from recent works on cloaking via anomalous localized resonance.
