Abstract : Described is a surface acoustic wave electromagnetic transducer (SAW EMT) having a meander line with progressively smaller spacing between conductors produces a surface, acoustic, traveling, exploratory, output signal that is greatly dispersed, when excited with a pulse electrical signal; and a corresponding compressed electrical output signal is produced from a received acoustic signal. The transducer may be used either to transmit or receive signals. (Author)
