摘要
文中研究了在时间上采用5级4阶差分、空间上采用4阶差分的高阶辛时域有限差分(SFDTD)数值方法,给出其三维差分公式.将吸收边界条件应用于微带天线的计算中,计算了微带贴片天线的回波损耗及输入阻抗等.计算结果证明,该方法的精确性和正确性.
In this paper, a high-order symplectic finite difference time domain schemes is constructed for Hamilton system, a three-dimensional fifth-stage forth-order formula of iterative algorithm is proposed. The Return loss and Input impedance of microstrip antenna be calculated using Symplectic finite difference time domain method（SFDTD） and absorbing boundary condition. Calculating results have shown that the SFDTD method is accurate and effective.
