I don't know who decided to use the EMdrive illustration on this, the paper uses a different concept altogether. Whereas the EMdrive bounces RF around to "achieve thrust", this uses charged particles in a helical beamline... the tricky bit is to efficiently transfer 165 Megawatts into a beam to accelerate it, then couple that power back out to recover it. Needless to say, there are some stiff engineering challenges involved. ;-)
