Abstract

Theoretical procedures are presented for the determination of the internal and the near-surface electromagnetic fields for an arbitrary monochromatic field (e.g., a focused laser beam) incident upon an irregulary shaped, axisymmetric layered particle. The layered spherical particle solution is also given as a special case of the general solution. Systematic calculations are presented that demonstrate the effects of particle shape and incident focused-beam orientation on the electromagnetic-field distributions.
