Manifestation of extremely high-Q pseudo-modes in scattering of a Bessel light beam by a sphere
The exact analytical solution of Maxwell equations for a Bessel light beam scattered by a sphere is found. Scattered power, stored energy, and a generalized Q factor as a function of frequency, the sphere radius, permittivity, and the Bessel beam angle are found. On the basis of this solution, modes …
