电磁波的衍射

Diffraction of Electromagnetic Waves

Ulrich Brosa

摘要:

本文发展了由标量表示求麦克斯韦方程组解的一般方法,并将其应用于电磁波的衍射问题。基尔霍夫积分的修改,以提供明确的表达式,这些代表。然后使用二维固定相方法评估相应的积分。迄今为止未知的公式的偏振出现,以及通过衍射成像。给出了描述圆形光阑后的菲涅耳衍射的公式。

英文摘要:

The general method to obtain solutions of the Maxwellian equations from scalar representatives is developed and applied to the diffraction of electromagnetic waves. Kirchhoff's integral is modified to provide explicit expressions for these representatives. The respective integrals are then evaluated using the method of stationary phase in two dimensions. Hitherto unknown formulae for the polarization appear as well as for imaging by diffraction. Ready-to-use formulae describing Fresnel diffraction behind a round stop are presented.
