运用傅立叶光学理论建立高斯光束的离散化模型 ,并用这个模型计算了双弯曲金属波导的传输效率 .结果表明 :注入激光的偏振方向与波导长轴方向一致时的传输效率远高于与波导短轴方向一致时的传输效率 .为双弯曲金属波导的应用提供了理论依据 .
The discretization model of Gaussian beam was established by using Fourier optics theory, and the transmission efficiency of the double curved metal waveguide was calculated by this model.The results show that the transmission efficiency when the polarization direction of the injected laser is the same as the long axis of the waveguide is much higher than that of the short axis The transmission efficiency when the direction is consistent, which provides a theoretical basis for the application of the double curved metal waveguide.
