研究了存储在二维光子晶体板中的电磁场引起的辐射力。我们考虑了两种不同类型的光子晶体腔，即双层板腔结构和气槽腔结构。在双层结构中，感应力是吸引还是排斥取决于存储电磁场分布的空间对称性。对于气槽结构，我们表明在板之间产生水平吸引力，并且在这里考虑的情况下，它可能比双层结构更强。光子晶体板上的感应力非常强，可以用微机电系统技术进行实验检测。一个基于耦合谐振器的简单物理模型很好地描述了这些结果。
Radiation force induced by an electromagnetic field stored in a two-dimensional photonic crystal slab is examined. We considered two different types of photonic crystal cavities, namely, double-layer slab cavity structures and air-slot cavity structures. With double-layer structures, induced force is attractive or repulsive depending on the spatial symmetry of the stored electromagnetic field profile. For air-slot structures, we showed that a horizontal attractive force is induced between slabs, and it could be stronger than that for double-layer structures in the case considered here. The induced force on a photonic crystal slab is so strong that it can be detected experimentally with the microelectromechanical systems technique. A simple physical model based on a coupled-resonator well describes these results.
