Yep, you can buy that sheet material on Amazon, etc. at a reasonable price. But it only shows magnetic field, not E. And not very high freq. magnetic field, I would imagine... It's essentially ferrofluid trapped in a sheet.

A special film was placed over the DUT and a video camera is used to view the electomagnetic emissions.
