3)  receiving antenna
接收天线
1.
An equivalent circuit for receiving antennas, which is composed of open-circuit voltage source and radiation impedance, is derived rigorously from electromagnetic boundary conditions based both on reciprocity theorem and the concept of reaction.
从场的观点出发,利用"反应"概念并结合互易定理严格证明了接收天线可以等效为传统基于开路电压的等效模型,并指出了当电场分别与接收模式下和发射模式下的电流作反应时,将得到不同的等效电路参数;结合偶极子天线的数值例子,说明了传统的开路电压模型在接收系统的分析中更为方便、合理。

补充资料:差值傅里叶法
分子式:
CAS号:

性质:在晶体结构分析中广泛应用的一种技巧。用它可在扣除先解析出已知原子坐标的基础上不断搜索待解析、未知原子的空间位置。设|F′c|与φ′相应为根据已知重原子或部分原子或非氢原子的坐标算得的结构因子模与位相的计算值,|FO|是结构因子模的实测值,则差值电子密度函数△ρ按下式进行计算由△ρ傅里叶级数的计算结果中可导出已知原子以外的原子坐标信息。因上式中傅里叶系数与结构因子模实测值与计算值的差值相关,故称作差值傅里叶法。
