Experimental and numerical studies of the plasmonic resonance of a low-pressure hemispherical plasma discharge in the upper VHF band

This paper aims to present investigations of the plasmonic resonance of a hemispherical plasma discharge in the high VHF band. First, this plasmonic resonance is experimentally studied by illuminating the plasma discharge with an incident plane wave and by measuring its response using a coaxial probe located directly inside the plasma. In order to validate the experimental results, a numerical study is then proposed by coupling plasma and electromagnetic simulations.
