摘要
在三维柱坐标系下推导了麦克斯韦方程组在完全匹配层(PML)吸收边界条件中的时域有限差分(FDTD)格式并编程实现.然后用一种简便的线性插值法给出了在柱坐标系下由近场到远场转换的FDTD计算方法.最后用这种方法对脉冲天线的远区辐射场进行了数值模拟.
In this paper, the finite-difference time-domain formation of Maxwell's equation is deduced and coded in perfectly matched layer (PML) in 3-D cylindrical stretched coordinates. Then, The conversion from near field to far field is completed with FDTD method in cylindrical stretched coordinates by means of a convenient linear interpolated method. In the end,the far field simulation of impulse antenna is given.
