| 摘 要： | 为降低传输过程中的损耗，加强介质加载等离子体波导的模式场约束，并且优化等离子体波导的传输性能，对基于介质加载的表面等离子体波导的传输特性做了进一步的研究，设计了一种脊背型介质加载等离子体波导，并对其模式场分布及其传输参数随波导中的几何参数与电磁参数的变化关系做了相应的研究。仿真结果得出:基模的电场分量主要分布在该结构的金属/介质层1界面。该模式的传输特性，随着该波导的几何参数的变化而发生相应改变，因而可以通过改变这种结构的几何参数，对场实现有效控制，使其局域性明显增强。

| Abstract: | In order to reduce the transmission loss, strengthen the medium loaded plasma waveguide mode field constraint and optimize the plasma waveguide transmission performance, a further research on waveguide transmission characteristics of the dielectric loaded surface plasmon was studied. A waveguide with spine type medium load plasma was designed and the relationship between the geometric parameters and the geometrical parameters of the waveguide in the mode field distribution and its transmission parameters were studied. The simulation results show that the electric field component of the base mode is mainly distributed in the metal/dielectric layer 1 interface. As a result, the transmission characteristic of the model changes with the variations of the geometrical parameters of waveguide. Hence, the field can be effectively controlled by shifting the geometrical parameters of the waveguide and localization can be enhanced obviously. |
