Magnetostatic wave transducers
Abstract
The coupling of magnetostatic wave energy into and out of ferrimagnetic films using flat current carrying conducting strips is discussed. An electrical equivalent circuit model is developed, from which insertion loss is derived for a magnetostatic wave delay line, made up of two multi-element transducers and a yttrium-iron garnet film. Experimental and theoretical comparisons are made and the range of validity of present magnetostatic models is discussed.
