“…These losses determine the distance which the spin waves can travel before they become too small to be detected. There have been both experimental and theoretical studies of propagation loss [27][28][29][30][31][32]. A phenomenological loss theory determines the upper and lower limits of propagation losses for different propagation modes of MSSW [32,33].…”

equally to this work.Abstract The authors have investigated the possibility of utilizing spin waves for inter-and intra-chip communications, and as logic elements using both simulations and experimental techniques. Through simulations it has been shown that the decay lengths of magnetostatic spin waves are affected most by the damping parameter, and least by the exchange stiffness constant.The damping and dispersion properties of spin waves limit the attenuation length to several tens of microns. Thus, we have ruled out the possibility of inter-chip communications via spin waves.Experimental techniques for the extraction of the dispersion relationship have also been demonstrated, along with experimental demonstrations of spin wave interference for amplitude modulation. The effectiveness of spin wave modulation through interference, along with the capability of determining the spin wave dispersion relationships electrically during manufacturing and testing phase of chip production may pave the way for using spin waves in analog computing wherein the circuitry required for performing similar functionality becomes prohibitive.2

“…In [18] it was shown that for a sufficiently extended region of interaction of the SMSW and SAW (as fulfilled in our experiments), the width of the resonance curve, measured at the level of 3 dB, is equal to the dissipation parameter of the SMSW. The attenuation parameter, δω, of the SMSW is determined mainly by the width of the ferromagnetic resonance line, 2ΔH, of the material in which the wave propagates [20]. The width of the resonant curves (magnonic band gaps), as seen in figure 3, is strongly changed at input powers higher than −5 dBm.…”

Experimental results on the influence of the intensity of surface magnetostatic spin wave (SMSW) on its propagation in the dynamic magnonic crystals (MCs) created by surface acoustic waves (SAW) propagating in yttrium iron garnet (YIG) film on the gallium gadolinium garnet (GGG) substrate are presented. The shift of the resonant frequency of the SMSW reflections (frequency of the magnonic gap) and widening of the resonant reflection curves (increasing the width of the magnonic band gap) from their former meanings (3730 MHz and 5.25 MHz, respectively) were observed at 20 MHz SAW of 20 mW in biasing magnetic field of 640 Oe at input microwave power exceeding the threshold value of −5 dBm. At the input power of 10 dBm, the deviations of the magnonic gap frequency and of the width of the SMSW resonant reflected curves reach the values of 5 MHz and 2 MHz, respectively. At a frequency of 3730 MHz, a decrease in the reflection coefficient of the SMSW was observed at the input powers above the threshold. These results may be useful in investigations of MC and for creating new nonlinear signal processing devices.

The adoption of non-linear magnetic devices in Radio Frequency (RF) systems has been relatively slow due to their unique characteristics that do not lend themselves well to traditional design tools and methodologies. Herein we present the practical considerations in employing such devices in modern RF system design with an emphasis on realizable improvements in performance and adaptability in addition to the common design methodology that has been adopted to account for their unique behavior. Specifically, this article begins by presenting how a standalone nonlinear device such as a Frequency Selective Limiter (FSL) can enable a higher-level subsystem such as the Frequency Selective Canceller (FSC). This discussion sheds light on the importance of characterizing the behavior of an FSL and how this behavior is different from other, more traditional RF components such as a Pin Diode Limiter, as explained in the second part of the article. Lastly, a Magnetostatic Wave (MSW) delay line that leverages the recent advancements in non-linear magnetic device design is introduced in order to provide an attractive alternative to traditional delay lines. A more complete understanding of system-level performance benefits and device-level functionality will undoubtedly facilitate the widescale deployment of nonlinear magnetic devices to help mitigate spectrum congestion challenges faced by modern and future RF systems.INDEX TERMS Frequency selective limiter, analog signal processing, magnetostatic surface waves, receiver front-end, linearization techniques, delay lines.
