[远场]CST MWS远场方向图结果中的tot.effic表示什么？

仿真天线时输出的远场3D图形。 ]b5%?^Z#  
结果中的 rad.effic 是不是 辐射效率 = 辐射功率/净输入功率？ ~xsb5M5  
还有个 tot.effic 表示 .. *93l${'

谢谢了，但是我装的CST 2009的Help用不成。 e:occT  
总是出错

应该怎么解决help出错这个问题?

是不是装得什么“精简版”的CST？这年月外行人乱精简，真正有用的东西被精简了……。 7H.3.j(L

替你抄点儿吧： VkFMr8@|  
Radiation efficiency: The antenna radiation efficiency is defined as the ratio of gain to directivity or equally the ratio between the radiated to accepted (input) power of the antenna: 42M_ %l_

Total efficiency: The total efficiency is defined as the ratio of radiated to stimulated power of the antenna:

Compared to the input power, the stimulated power considers any occurring reflections at the feeding location.

这个我也不知道~~~~~~
