A new formalism is developed for diffraction-free vector beams in free space. The solutions of Maxwell's equations are separated into two polarization modes, TE and TM. We discuss the validity of the method by applying it to a particular solution, the vectorial Bessel beam of order m.
一种新的自由空间无衍射矢量光束形式被发展出来。麦克斯韦方程组的解被分离成两个偏振模式,TE 和 TM。我们通过将其应用于一个特殊解,即矢量贝塞尔光束的 m 阶,来讨论该方法的有效性。
