Summary

Story summary

Researchers at RPTU Kaiserslautern-Landau demonstrated a new physical effect using acoustic frequency filters that could boost future communications, including 6G.
They show small sound waves can couple with spin waves in yttrium iron garnet to form hybrid waves in the gigahertz range.
Supported by the European Research Council and the German Research Foundation, the work highlights agile, tunable filters for flexible signal control, published in Nature Communications.
