Abstract
A magnetostatic wave structure in which magnetostatic wave signals are coupled between discrete magnetostatic wave elements without the use of microstrip transducers. This structure consists of a plurality of blocks of ferrimagnetic material in which each block has an edge close enough to an edge of another block that a magnetostatic wave in the first of these blocks couples across the gap between these two edges into the second of these blocks. Linear and nonlinear configurations are presented that include a band pass filter.
