报告摘要：We shall present a story of analytical light scattering theories, namely generalized Lorenz-Mie theories (GLMTs) for various kinds of particles, since the first paper devoted to the issue in 1982. After the GLMT stricto sensu devoted to the interaction of laser beams with homogenous Mie particles, other GLMTs have been studied by the author for multilayer particles, aggregates and assemblies of spheres, spheres with internal spherical inclusions, cylindrical particles with circular and elliptical cross-sections, and spheroids. In such theories, the illuminating beams are encoded in sets of coefficients, named beam shape coefficients (BSCs), which may be evaluated using various methods. Applications concerned optical particle characterization (the original motivation), calculations of optical forces and torques (mechanical effects of light), internal resonances (whispering-gallery modes, morphology-dependence resonances, plasmons), among others. A recent topic concerns the transfer of results obtained in the framework of the GLMT to acoustical (more generally scalar) scatterings, including the design of a scalar localized approximation procedure to the evaluation of acoustical (more generally scalar) beam shape coefficients.
