Point source in 3D COMSOL, RF module

Hi guys,
I'm trying to simulate the near-field behaviour of a super-scatterer in 3 dimensions. I learned how to do the 2D case from this thread:
www.edaboard.com/thread118739.html
But I'm not able to do the same for the 3D case. More specifically for the application mode: 3D->RF Mod->EM Waves->Harmonic propagation
Defining a point in 3D space is still possible, but the option Physics->Point Settings appears to have been grayed out and can't be selected whether or not the defined point is.
My aim is just to create an isotropic radiator. How should I proceed on this?

Hi,
Has anyone experienced such a problem?
I have the same problem, I need to use point source for 3D calculations in RF module. What can be done as an alternative for point source? I don't know if a line source can be used instead of point source.
Thanks in advance,
Elif

Hello,
Electric and magnetic point dipoles are supported in version 4 of the RF Module.

Hi,
I suppose you have solved the problem. Could you please explain more in detail how I could model a point source or a filamentary currents in a 3D scenario?
In 2D it is just matter of drawing a point and then add a point source there but in a 3D scenario Comsol does not allow you to do that.
Thank you for your help.
