关于麦克斯韦方程组无衍射解的物理意义的注记
Remarks on the Physical Meaning of Diffraction-Free Solutions of Maxwell Equations
摘要：
本文证明了电磁辐射源在波区不可能发出无衍射光束。贝塞尔$J_0$ $ϕ$不变光束甚至在中间区也不保持。这些结果否定了最近在文献中发表的声明。
英文摘要：
It is proved that a source of electromagnetic radiation cannot emit a diffraction-free beam at the wave zone. A Bessel $J_0$ $ϕ$-invariant beam does not hold even at the intermediate zone. These results negate claims published recently in the literature.
