摘　　要：提出一种电磁场递推算法来分析微纳光学元件体内电磁场的传输.该方法基于Maxwell方程组和电磁场横向的边界条件给出了严格解.以高斯光束在亚波长矩形浮雕光栅体内的传输为例,分析了非匀幅光束在微纳光学元件体内的传输.A recursive algorithm for electromagnetic fields propagating in micro-nano optical elements is proposed in this paper. This method is based on Maxwell＇s equations and the continuity of tangential components of the electric and magnetic field vectors,and gives an exact complete solution. Taking the propagation of Gaussian beams in the sub-wavelength rectangle relief grating as an example; we analyze the propagation of beams with non-uniform amplitude in micro-nano optical elements in detail.
