APPARATUS FOR PROVIDING EFFICIENT COUPLING BETWEEN RF ELECTROMAGNETIC ENERGY AND PHONON ENERGY BY MAGNETOSTRICTIVE EFFECT COMPRISING: (A) MEANS FOR SUPPORTING SAID RF ELECTROMAGNETIC ENERGY HAVING A FIRST CONDUCTOR AND A SECOND CONDUCTOR SPACED THEREFROM, SAID ELECTROMGNETIC ENERGY EXHIBITING AN RF ELECTRIC FIELD EXTENDING BETWEEN SAID CONDUCTORS AND AN RF MAGNETIC FIELD EXTENDING AROUND SAID FIRST CONDUCTOR, (B) SAID FIRST CONDUCTOR HAVING A REGION OF REDUCED SURFACE AREA FOR INCREASING THE DENSITY OF THE RF MAGNETIC FIELD AROUND SAID REGION, (C) A THIN FILM MAGNETOSTRICTIVE MEDIUM HAVING A D.C. MAGNETIZATION ORIENTED IN A PREDETERMINED DIRECTION, SAID MEDIUM BEING POSITIONED PROXIMATED TO SAID REDUCED SURFACE AREA REGION SO THAT, THE INCREASED DENSITY FIELD IS COUPLED THROUGH SAID MEDIUM IN A DIRECTION APPROXIMATELY PARALLEL TO THE PLANE OF THE PRINCIPAL SURFACE THEREOF FOR PROVIDING EFFICEINT COUPLING BETWEEN SAID RF ELECTROMAGNETIC ENERGY AND PHONON ENERGY SUPPORTED BY SAID THIN FILM MEDIUM.
