How to use optimization mask in FEKO

H_Kazemi_2000

Hello,

I have a couple of questions regarding optimization mask in FEKO.

In optimization mask, there are X and Y. Recently, I have watched the video in the following link:

https://youtu.be/AxjK4xUl-pM?si=jJZl1ZErpoVoeZuF

Where the engineer specified some specific frequencies and s-parameters in X and Y columns, respectively. But my question is:

1- how feko understands that column X, represents the frequency? For example, it maybe theta or other parameters.

2- Even imagine the situation that the the engineer wishes to define a 3D plot, with two variables. So, there must be three parameters in mask definition; two of them for Variables, and one of them for labels (For instance, Imagine the 3D plot of gain for an antenna). Is there any chance to have a 3D mask?

Hello @H_Kazemi_2000,

When the mask setting is applied for the specific optimization goal value (quantity), the X and Y follow the way the goal value is defined. In the video, the reflection coefficients from the voltage source are calculated w.r.t the frequency, so X= frequency and Y= reflection coefficient automatically.

I don't think the current 2D mask can define all 3D axis (X, Y, Z) with one mask, but 2D gain plot is possible as shown below in the Feko user guide.

You can add another gain goal/mask to include different angle cuts. (Like one is a horizontal cut plane and the other is a vertical cut plane.)

Best regards,
