对平面波正入射情况下正三角波导的传输特性进行了理论分析与探讨,求解出该波导系数的解析结果,从而得到该波导任意长度截面的光场分布,并借助于数值方法模拟其结果.结果表明,在波导的z=L0/6和z=L0/9截面的光场分布具有三重轴对称性.

The transmission characteristics through a mental equilateral triangle waveguide in plane wave normal incidence situation are discussed theoretically.The precise results of the coefficients in this waveguide are solved,then the random length section field distribution of this waveguide can be obtained.With the help of numerically analyzing,it is found that the output field distribution from the z =L0/ 6 and z =L0/ 9 section has three axial symmetry.
