I am trying to design an antenna that is focused in the near-field. I would like to optimize the antenna's power density on a plane at a distance of 1 m from the antenna (which is around 10*wavelength) and this location lies in the near-field of my antenna due to the antenna's electrical size. The near-field simulation setup allows me plot the fields on a sphere or a line but not on a plane.
I read somewhere that I could place a non-model plane at a distance of 1m from my antenna and plot the fields on it, but then this kind of simulation would be computationally expensive due to the size....
I was wondering how I would go about performing this simulation?

I had a similar goal and was able to use Savant to simulate field strength on a plane. Here's what my sim looked like:
the purple blocks are concrete buildings and the antenna is located above the middle building as shown by the torus pattern of a dipole. I was trying to simulate the field strength at ground level. You should be able to do the same thing in your case and use a y-z plane or something.

Great! Thank you! Did you import the torus shaped pattern from an HFSS simulation?

I used one of the default dipole models in Savant actually, and specified that the radiation pattern be shown.
