2.5D-FDTD数值算法的建立和模拟
The establishing and simulation of 2.5D-FDTD numerical algorithm
【摘要】 本文提出并建立了2.5D-FDTD数值分析方法;通过与解析解及常规FDTD算法的比较,验证了该算法的正确性,显示了该算法的优越性;通过加入三维矩形口径面超宽带天线,实现了对地下埋藏目标体的识别,进一步说明了该方法的可行性和实用性.
【Abstract】 This paper proposes and establishes the 2.5 dimension finite difference time domain(2.5D-FDTD)numerical analysis method.The comparision with analytical solution and conventional FDTD algorithm,confirms the correctness of the 2.5D-FDTD algorithm and shows the superiority.Simulation which applies the three-dimensional rectangular aperture Ultra wideband(UWB) transmitting antenna,realizes the identification of the buried object,and further proves the feasibility and usability of the 2.5D-FDTD algorithm.
