摘要:

电磁波的超分辨、超常透射、全吸收和局域化等现象正引起人们越来越多的关注。这些现象与不同的物理对象有关,通常在不同的背景下进行研究,有时相当复杂,物理方法。值得注意的是,所有这些看似无关的现象都源于同一个基本的物理机制--波与开放共振器的相互作用。在这里,我们表明,它是可能的,以一种统一的方式来描述所有这些影响,映射到一个简单的谐振器模型的每个系统。这样的描述提供了一个透彻的理解的现象,解释了所有的主要特点,其复杂的行为,并能够控制系统通过谐振器参数:本征频率,Q因子,和耦合系数。

英文摘要:

Superresolution, extraordinary transmission, total absorption, and localization of electromagnetic waves are currently attracting growing attention. These phenomena are related to different physical objects and are usually studied within the context of different, sometimes rather sophisticated, physical approaches. Remarkably, all these seemingly unrelated phenomena owe their origin to the same underlying physical mechanism - wave interaction with an open resonator. Here we show that it is possible to describe all of these effects in a unified way, mapping each system onto a simple resonator model. Such description provides a thorough understanding of the phenomena, explains all the main features of their complex behaviour, and enables to control the system via the resonator parameters: eigenfrequencies, Q-factors, and coupling coefficients.
