ABSTRACT:
A fluidic antenna is described, using an electromagnetic energy coupler, a non-metallic container coupled to the electromagnetic energy coupler, a fluid having charged particles moving through the non-metallic container at a predetermined rate, and a charge focuser disposed about the non-metallic container, wherein the electromagnetic energy coupler is configured to couple energy between the fluid and at least one of a transmitter and receiver, and the charge focuser is configured to adjust a cross sectional area of charged particles in the fluid to result in a fluid characteristic impedance that approaches that of a surrounding medium, thereby enabling at least one of launching and receiving electromagnetic energy.
