摘要
考虑到复杂介质会对电磁波传播过程中产生反射、吸收等影响,采用时域有限差分(FDTD)方法研究了二维情况下不同形状、不同深度、不同尺寸以及不同介质特性的地埋目标复杂介质对电磁反射波时频域特性的影响,并与一维修正FDTD方法进行对比,得到了类似的结果。两种方法都有可取之处。
Taking into account that the electromagnetic wave propagation in complex media have an impact on the process of reflection and absorption,we used finite difference time domain( FDTD)method to study of different shapes,different depths,different sizes and different dielectric properties of two-dimensional case buried target complex media to the time-domain and frequency-domain characteristics influence on the electromagnetic wave reflection,and compared it with a repair positive FDTD method,it yielded similar results. Both approaches have their merits.
