摘要
对正三角形波导中的图像传输问题进行了理论分析与探讨，推导出正三角形波导的自成像周期，并借助于数值方法模拟其图像传输特性。数值结果表明：在1／3自成像周期截面的输出图像分成三个与输入图像一致的图像，其对称位置的图像相对于输入图像依次发生120°的旋转。
Abstract
Image transmission through an equilateral triangle waveguide is discussed theoretically. Self-image period in a mental equilateral triangle waveguide is derived;and image transmission on the waveguide is studied by numerical simulation. With the help of numerically analyzing,it is found that three output images form from one of three the self-imaging length of the waveguide,moreover,the symmetrical output images rotate 120°angles.
