摘要

在本文中，我们提供了一个理论描述的表面极化子的传播绑定到一个二维（2D）金属平面。具体来说，我们严格地讨论了如何获得包含二维平面的空间的标准正交特征向量。这些特征向量由一个独特的表面束缚模式组成，对应于二维表面极化（2dsp），以及一个连续的非束缚模式，称为辐射模式。我们证明，虽然辐射模式不能直接表征2dsp的传播，但它们在操纵2dsp的传播中起着重要作用。

Theory of two-dimensional surface polaritons and their propagation

In this paper, we provide a theoretical description of the propagation of surface polaritons bound to a two-dimensional (2D) metallic plane. Specifically, we rigorously discuss how orthonormal eigenvectors for the space including the 2D plane can be obtained. These eigenvectors are shown to consist of a unique surface-bound mode, corresponding to the 2D surface polaritons (2DSPs), along with a continuum of unbound modes, referred to as radiation modes. We demonstrate that although the radiation modes do not directly characterize the propagation of the 2DSPs, they play an important role in manipulating the propagation of 2DSPs.
