Applications of T-Matrix Method in Optical Tweezers and Its Progress
摘要
T矩阵法适合用来研究微粒尺寸与入射光波长相近时系统中光镊的捕获力。T 矩阵法只取决于散射微粒的形状、尺寸大小、折射率及微粒在坐标系中的位置,而不受入射场约束。主要简述了T 矩阵法基本原理和计算,综述了光镊中单个微粒、两个微粒及两个以上微粒捕获力和力矩的计算方法,并对T 矩阵法在光镊中的应用前景做了分析。
Abstract
The trapping force of the optical tweezers is studied using T-matrix method when the particle is in sizes comparable with the wavelength of the incident light.The T-matrix depends only on the composition、size、 shape and orientation of particles, independent of the incident field.The basic principles and the calculation methods of T-matrix method are reviewed.The calculations of trapping force and torque of the single particle and two or more particles using T-matrix method are summarized.The prospect provided by T-matrix method for optical tweezers is also analyzed.
