    "abstract": "We present a simple and unified classification of macroscopic electromagnetic\nresonances in finite arbitrarily inhomogeneous isotropic dielectric 3D\nstructures situated in free space. By observing the complex-plane dynamics of\nthe spatial spectrum of the volume integral operator as a function of angular\nfrequency and constitutive parameters we identify and generalize all the usual\nresonances, including complex plasmons, real laser resonances in media with\ngain, and real quasi-static resonances in media with negative permittivity and\ngain.",
