| 摘 要： | FDTD已广泛应用于微带问题的计算 ,本文在分析各种微带线馈电激励设置方式的基础上提出了一种新的激励设置方式 ,本方法不仅能计算Gaussian脉冲激励 ,也能计算正弦波激励。计算过程中 ,源平面无需切换成吸收边界。由于场区的划分使反射场自然从总场区分离出来。

| Abstract: | A novel method of microstrip line fed excitation source is presented in this paper to analyze microstrip problems by the finite difference time domain method (FDTD). Unlike previous excitation treatment, which can only be used to calculate Gaussian pulse incident wave, this method can be used to calculate Gaussian pulse incident wave and harmonica incident wave. It is not necessary to switch the source wall to absorbing boundary condition in the iterative process. Because of field zone division, reflected fields naturally separated from total fields. |
