The microplasma source was ~2 mmin diameter and ~10 mm long, being operated at around atmospheric pressures; the micronozzlewas a converging-diverging type, having a throat ~0.2 mm in diameter and ~1 mmlong. Numerical and experimental results with Ar as a working gas demonstrated that thisminiature electrothermal thruster gives a thrust of >1 mN, a specific impulse of ~100 s, anda thrust efficiency of ~10% at a microwave power of <10 W, making it applicable to attitudecontroland station-keeping maneuver for a microspacecraft of <10 kg.}, pages = {2013--2023}, title = {Microplasma thruster for ultra-small satellites: plasma chemical and aerodynamical aspects}, volume = {80}, year = {2008} }
