Fluid Frame Magneto-hydrodynamic Antenna

A rotating fluid frame Antenna consisting of conducting fluid (saline water) is radiating under controlled electric field and magnetic field conditions. Water molecules oscillate due to impact ionization inside the fluid and contribute to radiate energy. Resonant frequency depends on volume, type of fluid, shape of tube, chemical properties of fluid used, DC magnetic bias and electric bias conditions. The prototype model is presented with analytical and experimental solutions. Mathematical formulations have been set up in support of detailed study of MHD antenna. The radiation patterns and impedance in this class of antenna become function of conducting fluid velocity v, magnetic field intensity H and electric fields intensity E due to Centrifugal and Coriolis forces in MHD phenomenon. Here Poynting vector of the antenna is different from the conventional type because of additional velocity field is involved.
