  1. Hi, In my simulation ,I requested 3D far field patterns. After running the simulation, when checked the far-field output in postfeko I get the following error 'Error 16030: Does not contain axes which can be plotted on a 3D view '. I could not figure out how to solve this. Similarly, I can not find the near fields as POSTFEKO says 'missing data' . I am not sure how to fix this error. any help would be greatly appreciated..! Thanks
  2. Hi, I would like to know how we can relate near field solutions and reflection coefficients in the simulations of periodic structures. When I simulate the Jerusalem cross FSS model in the example guide, near field results above the structure are always greater than the incident field (which is 1 V/m). Moreover, when the reflection coefficients are requested on the plane positioned above the structure where near field results are calculated, there is no correlation between near field results and reflection coefficient results when they are plotted as a function of frequency. Since the reflection coefficient is basically Er/Ei, how should we interpret near field results and Er? Thanks.
  3. Hello, I did cartesian plot for my structure's near field and maximum field magnitude is around 80 V/m (please see the attached screenshot). When I exported the near field data, I noticed that field values are much smaller than what's plotted in Postfeko (1E-2 times smaller). I'm attaching the efe file and plot of z vs mag Ez using the data in it for your reference. These values should be same, but they are not. Can you please help me understand what Postfeko does when plotting near field on cartesian chart? Thanks in advance, dipole.efe
  4. I recently saw a presentation from FEKO (Attached) where we can plot Magnetic flux and Electric flux after we request Near Field, then in Post Feko we have to go to Near Field -> Quantities -> Electric/Magnetic Flux. But in my FEKO 2017 student edition I don't get the option o flux. Where am I going wrong ? You can go to slide 24 of attached ppt or have a look at it directly below.
