Abstract : Magnetostatic surface waves (MSSW) were propagated on a 1-inch diameter yttrium-iron garnet (YIG) thin film disc with adjustable coupling transducers. These adjustable transducers enabled the film to be rotated underneath in order to investigate crystallographic influence. Experiments are described and data is plotted for signal power, time delay, beam steering and frequency shifts. A correlation technique was used to evaluate the resulting data, which reveals a 60 dependence in some characteristics. (Author)
