“…The efficient control of heat is particularly challenging as the device components approach nanoscale dimensions 1,2 . In addition, energy efficiency in signal processing can require transforming one type of signal into another, e.g., the transformation of microwaves into acoustic phonons with piezoelectric elements 3 .

Transport of heat and hypersound with gigahertz (GHz) to terahertz (THz) phonons is crucial for heat management in electronics, mediating signal processing with microwave radiation, thermoelectrics, and various types of sensors based on nanomechanical resonators. Efficient control of heat and sound transport requires new materials, novel experimental techniques, and a detailed knowledge of the interaction of phonons with other elementary excitations. Wave-like heat transport, also known as second sound, has recently attracted renewed attention since it provides several opportunities for overcoming some of the limitations imposed by diffusive transport (Fourier’s regime). The frequency-domain detection of GHz-to-THz phonons can be carried out in a remote, non-destructive, and all-optical manner. The ongoing development of nanodevices and metamaterials made of low-dimensional nanostructures will require spatially resolved, time-resolved, and anisotropic measurements of phonon-related properties. These tasks can be accomplished with Brillouin light scattering (BLS) and various newly developed variants of this method, such as pumped-BLS. In the near future, pumped-BLS is expected to become useful for characterizing GHz topological nanophononics. Finally, second-sound phenomena can be observed with all-optical methods like frequency-domain thermoreflectance.

“…Using this introduced circuit has been expected to further enhance the RF-FE in 5G and 4G systems. Acoustic devices like RF duplexers and filters have been widely utilized in mobile handsets as a result of their electric performance features [60]. Nevertheless, the bottleneck is the way to transfer a lumped circuit model (LCM) into an acoustic resonator's structural parameters for RF circuit designers for employing design tools of RF circuits in designing SAW devices.…”

In recent years, with the rapid growth of communication technology and the necessity for Radiofrequency (RF) front-end devices, the one-port Surface Acoustic Wave Resonator (SAWR) turns out to be a significant component in the design of a SAW device. Hence, the present study concentrates on and around one-port multi-layer SAW resonators with their applications in communication systems. A comparative and critical analysis of various parameters is explored including temperature coefficient of frequency (TCF), Quality factor (Q-factor), phase velocity, impedance ratio, bandwidth, sensitivity, metallization ratio, etc. to discuss the advantage and disadvantages of conventional one-port multi-layer SAW resonator. Through the analysis, future research trends as well as the applications of one port multi-layer SAW resonator are also discussed. The study also explores that the one port multi-layer SAW resonator finds employability in various applications like multimedia and mobile communication, medical field sensing technology, broadband signal processing at high frequencies, etc. Thus, significant, and efficient parameters of the resonator can be easily identified through comparative and critical analysis. The outcome of this study will help the researchers to enhance their work in this specific field in the future.

“…To date, the majority of studies on PnCs and acoustic metamaterials has involved macroscopic structures aimed to affect Hz-kHz acoustic waves/phonons. Nowadays, however, there is a significant need in developing PnCs in the nanoscale and operating in GHz as well as THz frequency regimes. ,, Nevertheless, nanofabrication of hypersonic PnCs faces several practical challenges preventing their implementation in everyday devices. The patterning needs to be performed over large areas/volumes of matrices being CMOS compatible for easy integration without sophisticated instrumentation.…”

Multiband Hypersound Filtering in Two-Dimensional Colloidal Crystals: Adhesion, Resonances, and Periodicity

et al. 2020

The hypersonic phonon propagation in large-area twodimensional colloidal crystals is probed by spontaneous micro Brillouin light scattering. The dispersion relation of thermally populated Lamb waves reveals multiband filtering due to three distinct types of acoustic band gaps. We find Bragg gaps accompanied by two types of hybridization gaps in both sub-and superwavelength regimes resulting from contact-based resonances and nanoparticle eigenmodes, respectively. The operating GHz frequencies can be tuned by particle size and depend on the adhesion at the contact interfaces. The experimental dispersion relations are well represented by a finite element method model enabling identification of observed modes. The presented approach also allows for contactless study of the contact stiffness of submicrometer particles, which reveals size effect deviating from macroscopic predictions.
