help in CST

I want to know if I can draw exponential function curve in the CST curve creation , because I want to know how I can get the planar metal with exponential function bounding in the vivaldi antenna simulation.who can tell me . thanks a lot !

Yes, it's possible

Macros -> Construction -> Create 2D curve analytical.
Then go to history and edit the macro like:

Dim xxx As Double, yyy As Double

For xxx = start To stop STEP 0.5

yyy = Exp(xxx)

.LineTo xxx , yyy
Next xxx

Then you need to pick end points and close the "polygon" for filling..
Don't know why but sometimes CST crashes during playing with 2D analytical curves :)
