CST MICROWAVE STUDIO? checks the boundary cross-section and throws the error message "Parallel symmetry planes! No farfield calculation possible." in case that two or more infinite perfect electric sheets seperating the complete calculation domain into half spaces are detected.  To overcome this problem you can add additional space surrounding the complete calculation domain (the structure is regarded as finite) or you should shorten all (except one) sheets so that they are no longer touching the boundary.

The farfield information is calculated as a post processing step from the recorded electric and magnetic field information on the bounding box. Whereas S-parameters in general converge at an very early stage of the calculation, the farfield quantities are from a numerical point of view less robust and show a higher sensitivity to the the choosen accuracy / truncation error. We therefore recommend to increase the accuracy specified in the transient solver dialog from the default setting "-30dB" to at least "-50dB". Furthermore the minimum distance between the structure and the open boundary should be at least 1/8th of the wavelength, which corresponds well to the default settings of the "open (add space)" boundary condition at the center frequency. For lower frequencies of interest you should increase the distance accordingly (e.g. 1/4th). ^y6CV4T+

The antenna radiation efficiency is defined as the ratio between the radiated to accepted (input) power of the antenna. It is displayed in the lower left area of farfield plots and acts for loss-free structures as an indicator for the currently achieved accuracy. Values close to 1 (+/- 5%) are fine, otherwise you should check your settings, e.g. the specified accuracy or the size and position of waveguide ports. Please see also FAQ 103. hBqu,A

不错。  

            

谢谢搂主的资料！ zQ

我想请问一下，我在做Par.Sweep,想把每次仿真得到的 某个farfield probe的信息记录下来。可是在 2P0*NQ  
PostProcessingTemplete中，我找不到相应的模板。不知道大家有没有好的办法？

下下来学习一下哈！！

看看啊，应该不错啊。
