Plotting in air, postprocessing, 4.2a, RF module

Dear All,

I have some issue. I made some calculation of gold nanosphere on substrate, and now I want to plot normalized electric field.

BUt, thing is I want to plot emw.norm^2 not just on sphere, also I want to plot it in air, but as I see air is invisible. Everything is blue like there is no any enhancement very close around sphere, and I done some calculations (point evaluation etc) and I am absolutetly sure there is field. Also I simulated dipole antenna, and I want to plot field in the gap (so air), there is no nothing.


Is there some option to make air visible??

Thanks in advanced
