Numerical and experimental assessment of Vlasov antenna performance for high power microwave applications

This article presents the results of numerical and experimental evaluation of performance of the Vlasov antenna in view of High Power Microwave (HPM) applications. The impact of the antenna geometry on its parameters, i.e. shape of the radiation pattern and the directional gain, is shown. Also, critical values of the electric field intensity that can excite electrical discharge are determined and trouble spots of plasma generation within antenna geometry that can block HPM emission are also determined.
