In this paper, the electromagnetic (TE)- plasma interaction and the chlorine Discharge Global modeled in a standard rectangular waveguide WR 284 (72.14 mm× 32.04 mm) by COMSOL multiphysics provide to be a very good compromise between flexibility and work efficiency. 12 01 2021 22 27 10.55672/hij2021pp22-27 https://hscience.org/index.php/hij/article/view/12
