Abstract:

In the present paper, an analytical study has been presented to examine the acousto–electric interactions in piezoelectric inhomogeneous semiconductor quantum plasma. The analysis is made by deriving the quantum-modified dispersion relation and subsequently deducing the expression of gain coefficient of acoustic wave using quantum hydrodynamic (QHD) model for inhomogeneous semiconductor plasma. The linearly and quadratically varying plasma density profiles have been chosen to investigate the effects of inhomogeneity through density gradient. We address the role of quantum parameter-H, scale le

Abstract:

The article highlights the features of the formation and detection of acousto-electromagnetic information leakage channels caused by acousto-electric transformations in technical devices. These channels present a significant threat to information security, as they convert acoustic oscillations into electrical or electromagnetic signals that may carry confidential information. The primary focus is on the classification of acousto-electric and acousto-magnetic channels, which are divided into direct and modulation channels. Direct channels arise from the direct interaction of acoustic waves with

Abstract:

Electric vertical take-off and landing (eVTOL) aircraft are characterized by their unconventional wing and electric rotor configurations, which involve both side-by-side and tandem rotor configurations. These configurations create unique aerodynamic and acoustic flow-fields. We numerically investigate the interaction effects between rotor pairs as well as their individual and combined acoustic radiation. We examine horizontal and vertical spacing, rotor tilt angles, and forward flight effects. Performance is characterized by thrust coefficient, blade passage frequency (BPF) sound pressure leve

Abstract:

Porous treatments are more and more employed in presence of flow as passive noise control means to mitigate the generated noise. They are generally designed according to their acoustic dissipation properties under no-flow conditions. Nevertheless, in-flow porous treatments can alter the aerodynamic properties, modify the main acoustic source itself or even generate secondary acoustic sources. While most of the modelling methods (analytical, FEM, ...) are able to model the acoustic dissipation, they do not allow to model the interaction with the main source or the possible generation of spuriou

However, the diffraction takes place at some other angles (called “optimal” here), which are situated on the opposite sides to the Bragg angle.

It is shown that a second harmonic of plasma density perturbation is generated by the convective nonlinearity of both thermal plasma and energetic particles.

The work has been aimed at determining the dynamic electric polarization within the Z-section of a class 6 mm piezoelectric single crystal, deformed by surface acoustic waves (SAW), and estimating the sensitivity of the electrode pair of the inter-digit transducer in the mode of recording surface acoustic waves in Z-sections of the piezoelectric crystals. Methods and Methodology. The analysis proceeds from cons

Abstract:

Driven by increasing demands for a sustainable and eco-friendly future in aviation, distributed electric propulsion (DEP) systems have received much attention for their high aerodynamic efficiency. DEP systems of lower noise emissions are desired by customers and policymakers and therefore it is important to understand the aeroacoustics and interaction of distributed propeller systems. In this paper, the aeroacoustics of a simplified DEP system is numerically investigated. The system consists of two Mejzlik 2-blade-9 × 9-inch propellers that are distributed side by side, with a tip-to-tip dist

Abstract:

In the article was solved the problem of radiation of a sound by the electroacoustic transducer which is executed in the form of a thin spherical cover, using a pass-through method. The outer and inner surfaces of the shell are completely electroded. The application of this method provides an opportunity to avoid inaccuracies that arise during the traditional formulation of boundary conditions for acoustic mechanical fields, the use of equivalent substitution schemes and the absence of boundary conditions for the electric field in general. Given methodology eliminates these shortcomings by app

Abstract:

Аcoustoelectronics is one of the areas of acoustics, associated with the use of mechanical resonance effects and the piezoelectric effect, as well as the effect based on the interaction of electric fields with waves of acoustic stresses in a piezoelectric material. The main materials used in acoustoelectronics are ferroelectrics, which are mainly complex oxide materials. This article discusses the possibility of increasing the purity and homogeneity of ferroelectric materials, as well as softening the regimes of their synthesis using the solution extraction-pyrolytic method.

Abstract:

The photoresponse in multilayer graphene on a lithium niobate crystal (LiNbO3) was studied under the conditions of an electric potential applied to graphene and transmission of a surface acoustic wave (SAW). It is shown that the acoustoelectric current in graphene when irradiated with light either increases or decreases depending on the polarity of the potential applied to graphene. SAW causes the appearance of a periodic charge lattice in graphene, which enhances the interaction with incident light, which leads to an increase in the photoresponse.

Abstract:

We investigate bone conduction of sound in the human head through a fully coupled model based on the fluid–structure interaction. The model was simulated via hp-finite element approximation employing our latest finite element library. The transmission of acoustic energy through non-airborne pathways to the cochlea, the receptor that converts the mechanical signal into electric impulses sent to the brain, is still not fully understood. We believe that our methodology and presented numerical results provide an insight into this fundamental, long standing research problem.

Abstract:

An electric vehicle was subjected to on-road acoustic tests. A specific high frequency tone was perceived in a sound field dominated by wind and road noise. The car was instrumented with microphones which measured the noise inside the passenger compartment and with tachometers to record the motors rotational velocity with respect to time. Waterfall diagrams were generated by tracking the spectrums of noise from fixed time samples against the rpm of the motor. The analysis of the diagrams revealed that high orders, like the 24th and 48th were responsible for the sound. These orders represent th
