Nowadays-used semiconductor +limiters suffer from high electronic noise and switching delays when approaching the GHz range, +which is crucial for the modern generation of 5G communication technologies aiming to operate at +the EU 5G high band (24.25–27.5 GHz). The proposed solution is to use ferrite-based Frequency +Selective Limiters (FSLs), which maintain their efficiency at high GHz frequencies, although they +have only been studied at the macroscale so far. In this study, we demonstrate a proof of concept of +nanoscale FSLs. The devices are based on spin-wave transmission affected by four-magnon scattering +phenomena in a 97-nm-thin Yttrium Iron Garnet (YIG) film. Spin waves were excited and detected +using coplanar waveguide (CPW) transducers of the smallest feature size of 250 nm. The FSLs are +tested in the frequency range up to 25 GHz, and the key parameters are extracted (power threshold, +power limiting level, insertion losses, bandwidth) for different spin-wave modes and transducer +lengths. An analytical theory has been formulated to describe the fundamental physical processes, +and a numerical model has been developed to quantitatively describe the insertion losses and power +characteristics of the FSLs. Additionally, the perspective of the spin-wave devices is discussed, +including the possibility of simultaneously integrating three devices into one: a frequency-selective +limiter, an RF filter, and a delay line, allowing for more efficient use of space and energy.</description> + </descriptions> + <resourceType resourceTypeGeneral="Other">Asset</resourceType> + <language>eng</language> + <dates> + <date dateType="Created">2025-01-29T11:36:20.040Z</date> + </dates> + <subjects> + <subject>Magnetismus</subject> + <subject>Magnetism</subject> + <subject>ÖFOS 2012 -- NATURWISSENSCHAFTEN (1) -- Physik, Astronomie (103) -- Physik, Astronomie (1030) -- Magnetismus (103017)</subject> + <subject>ÖFOS 2012 -- NATURAL SCIENCES (1) -- Physics, Astronomy (103) -- Physics, Astronomy (1030) -- Magnetism (103017)</subject> + <subject>Frequency selective limiters (FSLs), Power limiting effect, Multi-magnon scattering, Yttrium Iron Garnet (YIG), Magnonics, Spin waves, 5G communication systems</subject> + </subjects> + <sizes> + <size>6878203935 b</size> + </sizes> + <formats> + <format>application/x-zip-compressed</format> + </formats> + <rightsList> + <rights rightsURI="http://creativecommons.org/licenses/by/4.0/">http://creativecommons.org/licenses/by/4.0/</rights> + </rightsList> +</resource>
