The status of magnetostatic wave devices
Abstract
The current status of magnetostatic wave (MSW) signal-processing technology based on transversal filtering concepts used in surface acoustic waves (SAW) is summarized. The physical properties and limits of magnetostatic waves propagating in epitaxial ferrite films such as yttrium iron garnet are discussed, and MSW devices are compared with SAW counterparts. Primary areas requiring further research are identified and projections for MSW technology limits are given.
