Spatial Fano resonance of a dielectric microsphere impinged on by a Bessel beam
Spatial Fano resonance of a dielectric microsphere impinged on by a Bessel beam
The general concept of Fano resonance is considered so as to show the possibility of this resonance in space. Using a recently found solution for a Bessel wave beam impinging on a dielectric sphere, we analyze the electromagnetic fields near a microsphere with different optical sizes and permittivity values. We …
