Localized plasmons (polaritons), exited in the obstacle by the incident light, are equivalent to the quasi-discrete levels, while the radiative decay of these excitations plays exactly the same role as tunnelling from the quasi-discrete levels for the quantum problem. Mie scattering of light by a spherical particle and an exactly solvable discrete model with nonlocal coupling simulating wave scattering in systems with reduced spatial dimensionality are discussed as examples.4 pages, 2 figuresOther Condensed MatterMesoscale and Nanoscale PhysicsSoft Condensed MatterOpticsFano resonances at light scattering by an obstacletext
