gas medium

At any rate, I could hear Rhodan directly, which indicated that a sound-conducting gas medium was present.

This contrasts with methods employing an excited solid, liquid, or gas medium, where the frequency is fixed and depends on the medium used.

Initially a glow discharge is initiated to ionize the background gas medium by making filamentary discharge.

When the pressure of the gas medium in which the microplasma is generated increases, the distance between the electrodes must decrease to maintain the same breakdown voltage.
