Non-thermal dielectric barrier discharge (DBD) plasma is obtained by applying a high _________ voltage between two _______ separated by a ________ material.

Non-thermal dielectric barrier discharge (DBD) plasma is generated through the application of alternating voltage between two electrodes that are separated by a dielectric material. The use of alternating voltage is critical because it creates an oscillating electric field, which facilitates the ionization of gas molecules in a way that avoids significant heating of the plasma, thus maintaining its non-thermal characteristics.

The electrodes serve as the sources of the electric field necessary for generating the discharge, while the dielectric material acts as an insulator, preventing the continuous flow of current and allowing for the buildup of charge. This configuration is integral to the production of plasma, as it promotes the formation of electrical discharges at lower energy inputs, enhancing the efficiency of plasma generation.

This understanding underscores why the correct answer emphasizes alternating voltage, electrodes, and dielectric material—all of which are fundamental to the functioning of non-thermal DBD plasma systems.
