[交流] 【交流】全矢量光线传输方法 已有4人参与

请教一下,哪位知道“全矢量光线传输方法(Fully Vectorial Beam Propagation Method)”,有没有基于这种方法的软件。

惭愧,只是听说过有这个理论,和课题不相关,觉得太难了,没有看过。

GrasaVampiro:不错,知道是关于矢量衍射理论的 2010-07-07 10:46:48
标量衍射理论公式就非常复杂,全矢量的光线传输方法得复杂成啥样呀

就是啊,但这种方法算耦合很好用的

留意到这么一篇,没研究。

Vector wave propagation method

Vol. 27, No. 4/ April 2010/J. Opt. Soc. Am. A 709

M. Fertig and K.-H. Brenner

In this paper, we extend the scalar wave propagation method (WPM) to vector fields. The WPM [Appl. Opt. 32, 4984 (1993)] was introduced in order to overcome the major limitations of the beam propagation method (BPM). With the WPM, the range of application can be extended from the simulation of waveguides to simulation of other optical elements like lenses, prisms and gratings. In that reference it was demonstrated that the wave propagation scheme provides valid results for propagation angles up to 85° and that it is not limited to small index variations in the axis of propagation. Here, we extend the WPM to three-dimensional vectorial fields (VWPMs) by considering the polarization dependent Fresnel coefficients for transmission in each propagation
step. The continuity of the electric field is maintained in all three dimensions by an enhanced propagation vector and the transfer matrix. We verify the validity of the method by transmission through a prism and by comparison with the focal distribution from vectorial Debye theory. Furthermore, a two-dimensional
grating is simulated and compared with the results from three-dimensional RCWA. Especially for 3D problems, the runtime of the VWPM exhibits special advantage over the RCWA.
