The non-paraxial propagation of electromagnetic wave fields seems to be a condition of the micro and nano-optics. At these scales, spatial correlation is unavoidable and occurs in two important features, i.e. the spatial coherence and spatially correlated polarization. It makes the description of the electromagnetic wave fields challenging in both mathematical formalism and physical interpretation. In this context, the algorithmic implementation of the model plays a crucial role, not only for the theoretical description but also for the experimental development, mainly by taking into account that the theoretical model is able to predict the field’s behavior and properties in experimental scenarios both accessible and still non-accessible by technology. In this paper, the basic theory of the spatially correlated electromagnetic wave fields is discussed. Its capabilities are illustrated by the predictions provided by a modular algorithm, which uses the experimental specifications as individual entries, in close resemblance to the experimental setup.

电磁波场的非近轴传播似乎是微纳光学的一个条件。在这些尺度上，空间相关性是不可避免的，并且出现在两个重要特征中，即空间相干性和空间相关性极化。它使电磁波场的描述在数学形式主义和物理解释方面都具有挑战性。在这种情况下，模型的算法实现起着至关重要的作用，不仅对于理论描述，而且对于实验开发，主要是考虑到理论模型能够预测实验场景中的场行为和属性。技术可以访问和仍然无法访问。在本文中，讨论了空间相关电磁波场的基本理论。它的功能通过模块化算法提供的预测来说明，该算法使用实验规范作为单独的条目，与实验设置非常相似。
