ABSTRACT The excitation of surface plasmon-polariton (SPP) waves was delineated for an interface of a metal and an obliquely mounted uniaxially chiral, bianisotropic material with optic axis making an arbitrary angle with the interface plane. Such a material can be fabricated as a parallel assembly of hellixes with the axis of the hellixes making an arbitrary tilt angle with the metallic substrate. The canonical boundary-value problem as well as the two prism-coupled configurations were investigated. The direction of propagation of SPP waves was restricted to be in the morphologically significant plane of the bianisotropic material that contains titled hellixes. It was found that the chirality parameter of the bianisotropic material has to have a magnitude smaller than a threshold in order for SPP waves to exist for all tilt angles. Also, the SPP wave can be excited in both prism-coupled configurations only by p-polarized plane waves.

由金属和倾斜安装的单轴手性、双各向异性材料的界面引导的表面等离子体 - 极化波

摘要 表面等离子体激元 (SPP) 波的激发被描绘为金属和倾斜安装的单轴手性、双各向异性材料的界面，其光轴与界面平面成任意角度。这种材料可以制造为螺旋的平行组件，螺旋的轴与金属基板形成任意倾斜角。研究了规范边值问题以及两个棱镜耦合配置。SPP 波的传播方向被限制在包含标题螺旋线的双各向异性材料的形态学重要平面中。发现双各向异性材料的手性参数必须具有小于阈值的幅度，以便 SPP 波在所有倾斜角下都存在。还，
