磁致双折射和二向色性对磁性液体薄片的光透射率弛豫特性的影响

Effect of magnetic field-induced birefringence and dichroism on relaxation behavior of light transmissivity in ferrofluids film

基于Xu等人的经典振荡磁偶极子模型和Matsumoto等人给出的双折射驰豫理论,研究了磁致双折射和二向色性对磁性液体薄片的光透射率弛豫特性的影响。理论推导了磁性液体的双折射和二向色性函数的偏振光透射率具体表达式,并进行了数值模拟计算。该问题的研究对磁性液体光学各向异性的深入认识以及相关磁性液体光学器件的应用具有一定的指导意义。

The purpose of this paper is to investigate the effect of magnetic field - induced birefringence and dichroism on relaxation behavior of light transmissivity in ferroiluids film in term of the Xu＇ s oscillating magnetic dipole model and the Matsumoto＇ s birefringence relaxation theory. The specific expression of polarized light transmissivity about birefringence and dichroism is theoretically deduced and numerically simulated. The study has a certain significance on deeper understanding of the optical anisotropy and re- lated application of ferrofluids.
