Abstract

This paper derives a generalized spherical harmonic description of Bessel beams. The spherical harmonic description of the well-known cylindrical Bessel beams is reviewed and a family of spherical Bessel beams are introduced which can provide a number of azimuthal phase variations for a single beam radial amplitude. The results are verified by numerical simulations.

摘要

本文推导了贝塞尔光束的广义球谐描述。回顾了著名的圆柱贝塞尔光束的球谐描述，并引入了一族球贝塞尔光束，它们可以为单个光束径向振幅提供多种方位角相位变化。结果通过数值模拟得到验证。
