Abstract

The diffraction of an electromagnetic wave from a round hole on an opaque screen is studied when there is no vacuum on the opposite sides of the screen, as is usually considered, but on one side there is a refractive medium and on the other—vacuum. The diffraction peculiarities due to the fact that the medium into which the wave penetrates from the vacuum have a refractive index different from one are revealed. The case of diffraction in an anisotropic medium with the property of birefringence is also considered.

来自真空和物质之间的圆孔的电磁波的折射率不同于一的衍射

摘要

当通常在屏幕的相对两侧都没有真空时，研究了不透明屏幕上圆孔的电磁波衍射，这通常被认为是，但一侧有折射介质，而另一侧有真空。揭示了由于波从真空穿透到其中的介质具有不同于之一的折射率这一事实而引起的衍射特性。还考虑了在各向异性介质中具有双折射特性的衍射情况。
