Microwave Discharges in Liquid Dielectrics

Abstract—A review is given on microwave discharges in liquid dielectrics—a relatively new direction in the physics and application of low-temperature plasma. The main types of experimental devices are described, and available information on the plasma parameters obtained by emission spectroscopy is presented. Examples of application of discharges in liquid dielectrics, such as solution of ecological problems and production of hydrogen, nanomaterials, and diamonds, are considered.
