Description
Summary:A glass tube filled with a low pressure gas can be used to create a plasma column that behaves as an antenna; with respect to a traditional metallic antenna, a plasma antenna shows several advantages, especially due to the possibility of creating or destroying the conductive medium simply by applying bursts of power to the tube discharge.A parametric investigation of the problem is needed to understand how plasma parameters are affected by the discharge condition (frequency and intensity of the pump signal, gas pressure, vessel dimensions and so on) and optimize them; in particular, plasma conductivity is the key parameter that has to be maximized defining the plasma "metallic" behavior.
