“…Several variables are possible in this method: the MW power at the moment of ignition can be higher, lower, or equal to the operating power; the gas flow, gas type, and gas pressure at the moment of ignition can be different from the operating conditions; the position of the impedance tuner(s) and hence the value of the reflected power at ignition can be different from that of the impedance tuning for operating the plasma at low reflected power. With this method, attention must be paid to the timing required for the insertion/retraction of the metal pin, its position outside the plasma zone, and its shielding so as not to create an antenna; − Autoignition-obtained by careful MW applicator design and reduced-height waveguide configuration, where the excitation system has a local impedance close to that of the plasma [10,19,23,24] ; − Auto-ignition at low pressure.…”

The use of electricity for the industry's transition to a decarbonized economy requires optimization of the energy transfer to deliver efficient, cost‐effective processes. Industrial demand for high‐density plasmas over a wide pressure range has stimulated the use of microwave plasma (MWP) applications. In high‐temperature processing, when microwaves of the correct frequency are absorbed by the plasma, the plasma particles absorb energy from the electromagnetic field and transfer it to the other particles through collisions, heating them. This rapid heating gives MWP properties that can be exploited to increase the conversion, selectivity, and/or energy efficiency of chemical processes. Here, we address questions raised by industrial users who wish to better understand the limitations of MWP applications.
