Acousto ionic radio antenna

Abstract

The present invention is a plasma antenna that uses an acoustic mechanism to accelerate the ions of the plasma, causing them to radiate electromagnetic energy. A resonant acoustic chamber surrounds the plasma body to produce acoustic pressure waves of very high amplitude and ion accelerations sufficient to generate significant radiation. The resonant chamber is made of a material that is relatively transparent to electromagnetic radiation. Communications information in the form of a modulated frequency is imposed on the signal generated by the plasma by adjusting the resonant frequency of the chamber by changing a parameter of the chamber such as its length or wall stiffness. Varying the acoustic driving force may be used to modulate the amplitude of the radiated signal. Phase modulation may be implemented by lining the ends of the chamber with a material that can quickly alter the position of its reflective face.
