Abstract
Described is an intrinsically multiplexed magnetostatic surface wave (MSSW) device comprising of a pair of transducers that couple to one or more plurality of ferrite films. In embodiments, the ferrite films may be provided as one or more of a YIG, Nickle Zinc Ferrite, Lithium Ferrite configured to simultaneously provide the MSSW device having an associated plurality of MSSW operational bandwidths. The concepts, structure and technique described herein may be used to provide broadband magnetostatic surface wave devices that employ intrinsic multiplexing techniques which enable customizable frequency responses over broad bandwidths.
