Example Sentences
"What's special about YIG is that it propagates a magnetic spin wave," says Olsson, referring to the type of wave created in magnetic materials when electrons spin in a synchronized fashion.
When exposed to a magnetic field, the magnetic spin wave generated by YIG changes frequency.
"By adjusting the magnetic field," says Xingyu Du, a doctoral student in Olsson's lab and the first author of the paper, "the YIG filter achieves continuous frequency tuning across an extremely broad frequency band."
In addition to being tunable, the new filter is also tiny -- about the same size as a quarter, in contrast to previous generations of YIG filters, which resembled large packs of index cards.
While YIG was discovered in the 1950s, and YIG filters have existed for decades, the combination of the novel circuit with extremely thin YIG films micromachined in the Singh Center for Nanotechnology dramatically reduced the new filter's power consumption and size.
