Abstract

It was established by Green and Wolf in 1953 that an electromagnetic wave can be characterized by a complex scalar potential, including its energy and momentum densities. In this paper, we show that, for electromagnetic beams, this scalar potential can be used to fully describe the beam's topology. We further demonstrate that this scalar potential can be used to characterize a partially coherent vector beam, and introduce a set of scalar Stokes-like parameters for this purpose.

表示电磁波束拓扑结构的标量势。

1953年，格林和沃尔夫建立了电磁波可以用复标量势来表征，包括它的能量和动量密度。在本文中，我们证明，对于电磁波束，这个标量势可以用来充分描述波束的拓扑结构。我们进一步证明了这个标量势可以用来表征部分相干矢量光束，并为此目的引入了一组标量斯托克斯参数。
