I'm a bit confused on how they know. Did the researchers build a couple, because there was a picture labeled Em Drive? Or is it all still theoretical, done using math, and the picture just show what it would look like or a prototype?

It's an actual prototype. The problem is that no one has a theoretical basis for why it would work, except for some mumbling about virtual particles.

...from which it is still thought to be impossible to extract energy to do work.
