Abstract
A magnetostatic wave (MSW) device for performing spectral analysis of an input signal containing signal components of very high frequency, well in excess of 1 GHz (gigahertz). An input transducer array couples the input signal to a magnetostatic propagating medium, such as a film of yttrium-iron-garnet (YIG), in such a manner that the array effectively provides multiple wave sources spaced along a predetermined arc on the propagating medium, and the waves combine constructively at frequency-dependent points in a focal region of the medium, spaced apart from the input array. Output transducers located at these frequency-dependent points generate output signals indicative of various selected frequency components of the input signal.
