傅里叶分布抛物方程法的准三维研究

Research of quasi three dimensional of Fourier split-step parabolic equation approach

文章介绍了二维抛物方程的傅里叶分步法,提出了一种基于二维方法的准三维研究方法。将三维图形分解为两个二维图形。首先通过二维方法解决圆锥的主视图(三角形)和俯视图(圆形)的电波传播问题,将主视图和俯视图的计算结果分别与参考文献[5]和HFSS中的模型进行对比,从而验证其正确性。该方法比二维的研究范围更广,同时比直接使用三维公式求解简单。

The two-dimensional （2-D） Fourier split-step parabolic equation approach is introduced, and the quasi-three-dimensional （quasi-3- D） wave propagation method based on 2-D is proposed in this paper. The 3-D patterning is divided into two 2-D patterning. The results of the main view （triangle） and the top view （circular） of the cone are calculated by 2-D approach, which are compared with the results of the refer- enee [ 5 ] and the HFSS to verify their correctness respectively. The quasi-3-D is more extensive than the 2-D approach, and it is simpler than the direct use of the 3-D formula.
