CST MWS远场方向图结果中的tot.effic表示什么？

rad. effic = Radiation Efficiency
tot. effic = Total Efficiency
CST MWS帮助文件《Farfield Overview》。
Help -> CST MICROWAVE STUDIO -> Post Processing -> Visualizing Results -> Farfield Overview

谢谢了，但是我装的CST 2009的Help用不成。
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……。
替你抄点儿吧：
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:



or



.
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
