Good results also verify the feasibility of forward modeling with two-dimensional finite difference time domain method (2d-fdtd).
良好的结果也验证了二维时域有限差分法(2d - FDTD)正演模拟的可行性。
Optical field in tapered optical fiber is numerically simulated using 2D finite-difference time-domain (FDTD) method, optical character in different cladding radius is expounded.
然后用时域有限差分法（FDTD）数值计算了锥形光纤光场分布，论述了在不同的包层半径处，光纤锥的光场分布特性。
