We present a bi-orthogonal approach for modeling the response of localized electromagnetic resonators using quasinormal modes, which represent the natural, dissipative eigenmodes of the system with complex frequencies. For many problems of interest in optics and nanophotonics, the quasinormal modes constitute a powerful modeling tool, and the bi-orthogonal approach provides a coherent, precise, and accessible derivation of the associated theory, enabling an illustrative connection between different modeling approaches that exist in the literature.

使用准正规模式对电磁谐振器进行建模

我们提出了一种双正交方法，用于使用准正规模式对局部电磁谐振器的响应进行建模，该模式代表具有复杂频率的系统的自然耗散本征模式。对于光学和纳米光子学中的许多感兴趣的问题，准正规模式构成了一个强大的建模工具，而双正交方法提供了相关理论的连贯、精确和可访问的推导，使存在于不同建模方法之间的说明性联系成为可能文献。
