Transient internal and scattered fields from a multi-layered sphere illuminated by a pulsed laser

This paper is devoted to the interaction between pulsed lasers and multi-layered spheres. Internal and scattered fields are described in a rigorous electromagnetic approach, when a 50 fs pulse illuminates a 80 μm diameter particle. Whispering gallery modes wave packets generation inside a core-mantl...

Description
Summary:	This paper is devoted to the interaction between pulsed lasers and multi-layered spheres. Internal and scattered fields are described in a rigorous electromagnetic approach, when a 50 fs pulse illuminates a 80 μm diameter particle. Whispering gallery modes wave packets generation inside a core-mantled sphere and effects of a refractive index gradient on scattered fields are in particular exhibited.
