摘　　要：基于厚度达到毫米量级的双面金属包覆波导,采用波长为785nm的激光入射到该波导金属耦合层上,激发波导中的超高阶导模,在波导正上方放置固定磁钢。在穿过波导中心的平行磁场作用下,选择合适的三个连续的导膜角,测定液体膜的折射率,得到磁流体折射率与磁感应强度大小的关系。Based on the sided--metal--coated waveguide of the thickness of millimeter with a wavelength of 785nm laser incident on the waveguide metal coupling layer, excite order modes in the waveguide and place just above the waveguide fixed magnet.In the parallel magnetic field passing through the waveguide center, select the appropriate three consecutive film guide angle, the refractive index of the liquid film was measured to obtain the relationship between the refractive index of the magnetic fluid and the magnitude of magnetic flux density.
