MAGNETOSTATIC WAVE DEVICE BASED ON THIN METAL FILMS, METHOD FOR MAKING SAME AND APPLICATION TO DEVICES FOR PROCESSING MICROWAVE SIGNALS

摘要

The invention concerns an integrated magnetostatic wave device comprising a substrate (1), a conductive ferromagnetic thin film (2) arranged on the substrate (1), a first transducer antenna (10) for receiving microwave electric signals, arranged parallel to said ferromagnetic thin film (2) proximate thereto to generate in said material, through inductive coupling, magnetostatic waves or spin waves, and a second transducer antenna (20) for transmitting microwave electric signals, arranged parallel to said ferromagnetic thin film (2) proximate thereto to be inductively coupled and deliver microwave electric signals when a magnetostatic wave reaches the ferromagnetic thin film (2) said second antenna (10) being located on the same side of the ferromagnetic thin film (2) as the first antenna (10) substantially coplanar thereto.
