I understand that they have an interesting method of using microwaves to produce plasma from water. They claim to have a "high" thrust and "high" specific impulse. Their Isp numbers are published, but apparently not thrust. Has there been anything published on that end? More about the company here: homepage, but it doesn't look like much in the way of technical specs
Probably, partial answer. Momentus has been published (slide #58) value of the thrust for its Vigoride Extended vehicle of 0.8 N (800 millinewtons) with 650 seconds Isp and total impulse capability of 2.000.000 N-s (for maximum "wet" mass of 700 kg).
Just to add to Peter Nazarenko's good answer on the thrust as the power requirement was also discussed in comments:
The electrical power required to feed the beam power of the thruster is P= T V/(eta 2) where eta is a combined efficiency factor comprising thermal losses from the thruster (20% - 50%) and electrical losses (maybe 5% - 10%).
Thus the absolute minimum, artificially setting eta to 1, Isp = 650s and Thrust = 0.8 thus electrical power = beam power = 650 * 9.81 * 0.8/2 = 2,550W.
