I describe three ways that the spatial properties of a wave propagation medium can cause dispersion, and propose that they should form the basics for correctly understanding and naming phenomena described as “spatial dispersion”. In particular, I emphasise the specific spatial properties which generate the resulting dispersive – i.e. spatially dispersive – behaviour. The properties are geometry, structure, and dynamics.

空间色散的新介绍：重新构想基本概念

我描述了波传播介质的空间特性可能导致色散的三种方式，并建议它们应构成正确理解和命名被称为“空间色散”的现象的基础。我特别强调特定的空间特性，这些特性会产生最终的分散（即空间分散）行为。这些属性是几何，结构和动力学。
