| 摘要: |
| 采用了结合完全匹配层(PML)吸收边界的时域有限差分方法(FDTD)分析了加脊喇叭天线的时域特性。利用环路积分方法(CP)处理曲线金属边界和脊间窄缝, 计算了天线的阻抗以及口径场的幅相分布, 结果表明, FDTD法分析天线时域特性是非常有效的。 |

| Abstract: |
| The impedance and radiation characteristics of ridged horn are calculated by using the FDTD method with PML absorbing boundary condition and CP method on treatment of curve PEC boundary and slot between ridges. The amplitude and phase for antenna field are given, and results show that this method is perfect. |
