I assume this is a stationary plasma field, that is kept at the ship. How
fast would such a sheet render useless after the power has been cut off?
When we would use it as retro mirror, it NEEDS to be loose from the starship.
We need to scale this thing up to many hundreds of square meters and several
meters thick (the radiation pressure is much higher).
