Abstract
We report the results of investigations of a continuous microwave discharge ignited in a quasioptical resonant cavity. We study a new phenomenon for such a discharge: a small-scale stratification of the plasma in the direction perpendicular to the electric field vector. This stratification is observed in a plasma with electron density higher than the critical density at the microwave frequency and is due to the development of a thermocurrent instability.
