【摘要】 基于电磁场理论,采用直接计算的方法证明了左手材料薄板波导中各个模式是相互正交的,即不同传播模之间、传播模与辐射模以及不同辐射模之间是相互正交的.这为研究左手材料薄板波导中的模式耦合奠定了基础.更多还原

【Abstract】 Based on the electromagnetic theory and by adopting the method of direct calculation, this paper proves that the modes of left-handed materials slab waveguide are orthogonal among each other, i.e. the fast waves, the slow waves, and the radiation modes are orthogonal among each other. This work provides a basis to study modes conversion in left-handed materials slab waveguide.更多还原
