利用170GHz毫米波在大气中产生等离子体后，观察到电离前沿在束通道中的传播。当毫米波功率密度大于75kWcm−2时，电离锋的传播速度为超音速。动量耦合系数Cm，推进脉冲的输入能量的比率，测量使用圆锥形和圆柱形的推力器模型。当电离锋以超音速传播时，记录到的Cm值大于350 NMW −1。
Propagation of an ionization front in the beam channel was observed after plasma was generated using a 170GHz millimeter-wave beam in the atmosphere. The propagation velocity of the ionization front was found to be supersonic when the millimeter-wave power density was greater than 75kWcm−2. The momentum coupling coefficient Cm, a ratio of the propulsive impulse to the input energy, was measured using conical and cylindrical thruster models. A Cm value greater than 350NMW−1 was recorded when the ionization front propagated with supersonic velocity.
