| 摘 要： | 在研究偶极子天线辐射的Sommerfeld半空间模型基础上，通过对构造模型的边界条件的改进，提出了建立功率吸收钳校准系统的新方法。它将一个复杂的开放系统的近场辐射问题转化为一个传输线路问题，用经典的传输线理论进行计算，建立了严格的吸收钳校准的数学模型，并给出相应的等效电路，数学模型的计算结果与实际校准的结果能很好符合，理论计算结果有较高的参考价值。 |

| Abstract: | Based on studying the Sommerfeld half space model of the dipole antenna radiation, and improving its boundary condition, a new method for establishing the mathematical model of the absorbing clamp calibration system is put forward.It converts a near radiation problem for complex opening system into an electrocircuit problem of transmission line, then the transmission line theory is used to calculate the absorbing clamp calibration system ,and its mathematical model is established. Its equivalent circuit is also given. The calculation result of the mathematical model is in good agreement with the actual calibration result, and this theoretical calculation result can be used as reference. |
