A superconducting microwave engine

Abstract

In this paper a new technique of electromechanical energy conversion is proposed. This technique would make use of the high Q's attainable in superconducting resonators to achieve direct mechanical to microwave energy conversion with a net efficiency greater than 90% a value which is far higher than that obtained by conventional techniques. In addition, if surface magnetic and electric field levels are limited by the critical fields obtained in fixed resonators, power densities would be achieved which are large enough to make such a machine a practical means both for generating microwave energy and for re-converting the microwave again to mechanical energy for power transmission purposes.
