摘　　要：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 .A discrete model of Guassian beam is established based on Fourier Optics principles. The transfer efficiency of dual bending waveguide is obtained by using this model. The results show that the transfer efficiency is much higher when polarization direction of injected laser coincides with the direction of long axis than with that of short axis of the waveguide. Futher more, it offers a theorical base for dual bending waveguide′s application.
