摘要
在通信系统中波导的设计向着多功能和可调制方向发展。波导基于等离子体金属材料在外磁场作用下设计平面波导。等离子体金属材料在外磁场作用下会产生表面等离子体激元和非互易传播双重功能。从基本的麦克斯韦方程和边界条件出发,详细推导了模式的色散方程,并根据模式特征进行了分类。波导具有明显的非互易传播和可调制的特性。
The waveguides with multi-functionalities and adjustability will be the object of waveguide design in communication system.A design of slab waveguide is given based on plasmonic metal material.Under external magnetic field plasmonic metal material posseses two functions including surface plasmon-polaritons and nonreciprocal propagation.Starting with basic Maxwell Equations and boundary conditions,the dispersion equations of the modes is derived and classified according to the mode features.Such waveguide clearly shows the property of adjustability and nonreciprocal propagation.
