There was also a great episode on antimatter engines recently by PBS Space Time.

The first one "220" has a nice discussion, in particular a comment by pfdietz:
> It increases the rate of production of neutral antihydrogen from antiprotons and positrons by a factor of 8. It doesn't increase the efficiency of production of antiprotons, which is the extremely inefficient, energy intensive part.

If you can electromagnetically trap enough antimatter to use it as fuel you could as well trap a miniature charged black hole that can be fed regular matter to produce power, which skips the whole inefficient part of making antimatter.

Depends. Do we know how to obtain a miniature black hole?

Miniature black holes would just evaporate. Antimatter wouldn't.

What form of power and through what principle?

Hawking radiation, I think. Yes, this is at best speculatively feasible.
