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