| 摘 要： | 从麦克斯韦方程出发,研究了在时间和空间上进行高阶差分的辛时域有限差分数值方法(SFDTD),给出其三维差分公式.将吸收边界条件有效地应用于微带天线的计算中,计算了一种微带贴片天线并给出了天线的回波损耗及输入阻抗等.计算结果证明了该方法的精确性和正确性.该方法对于天线优化设计及电磁散射计算具有一定的借鉴作用.

| Abstract: | Based on the Maxwell's equations,a high-order symplectic finite difference time domain schemes is constructed for Hamilton system,a 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.It is useful for small antenna design and electromagnetism calculation. |
