Abstract

The transfer of the electromagnetic field from a toric emitter to a receiver of same kind is expressed by a two-dimensional integral which can be split into two one-dimensional integrals. Each one-dimensional integral can be seen as a fractionnal Fourier transform whose order is related to the distance between the emitter and the receiver and to their principal curvatures. The knowledge of these orders is alone sufficient to solve practical problems (such as image formation) without explicit use of the integral formulae.

局部环形发射器和接收器之间的衍射。在散光系统研究中的应用
电磁场从环形发射极到同类接收器的传递用二维积分表示,该二维积分可分解为两个一维积分。每个一维积分都可以看作是一个分数阶傅里叶变换,其阶数与发射器和接收器之间的距离以及它们的主曲率有关。这些阶的知识本身就足以解决实际问题(如成像),而不需要明确使用积分公式。
