论文摘要
我们提出了使用标量电势的电磁场的描述,用于传播不变光束。获得了基本动力学量:能量密度,poynting载体和麦克斯韦(Maxwell)应力张量。例如,所有这些量都是针对贝塞尔束明确计算的,贝塞尔束是具有圆柱形对称性的不变光束。
We present a description of the electromagnetic field for propagation invariant beams using scalar potentials. Fundamental dynamical quantities are obtained: the energy density, the Poynting vector and the Maxwell stress tensor. As an example, all these quantities are explicitly calculated for the Bessel beams, which are the invariant beams with circular cylindrical symmetry.
