The gain increase of a shortened horn antenna filled with a metamaterial structure was confirmed in numerical and experimental investigations reported in recent papers. All described embedded structures are multilayer grids or wires, optimized for one single frequency of operation. This paper presents first numerical studies of a plasma-filled horn. A strong focusing effect was observed.
