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

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

Abstract:
The interaction of beam driven solitons is studied in an unmagnetized plasma, comprising (r,q) distributed hot electrons, cold inertial electrons, warm electron beam and static ions. For this purpose, fluid equations are solved to obtain four distinct roots of linear dispersion relation which vary with beam speed. For small-amplitude limit, the standard Korteweg-de Vries (KdV) equation is derived that admits soliton solution and critical condition gives rise to modified KdV equation (mKdV). The overtaking interaction of KdV and mKdV solitons is studied by Hirota method, while the head-on collision (HOC) by the Poincare-Lighthill-Kuo (PLK) technique. The analytical expressions of phase shifts are examined for the plasma parameters, namely density, temperature, and velocity of beam electrons. In contrast to Hirota method, the PLK method provides the linear sum of the solitons at the point of interaction. However, despite this limitation, PLK technique is only analytical technique available to study HOC. The relevance of this model is interesting to understand tripolar electric field structures in Earth's Auroral region, which may be associated to the interaction of EASWs in space plasmas.

Abstract:
Abstract It was Landau (1933) and, later, Pekar (1946, 1949) who speculated that an electron moving within a polar crystal should experience self-trapping due to strongly interacting with the polarization fields arising from the lattice perturbations created by the electron. These speculations later led to the concept of the polaron as a quasi particle, identified as an electron, dressed in its own polarization cloud and moving within the polar crystal. Here we shall not dwell on the polaron problem (Devreese 1972) since our main concern will be with the weak coupling (perturbative) regime between the electron and the lattice polarization fields. In ionic or partially ionic lattices, electric polarization is largely associated with anion-cation pairs whose relative motion characterizes the optical modes of vibrations. The quanta corresponding to the optical modes, also called optical phonons, have relatively large energies compared with the acoustic modes and so the scattering process in which the electron and the lattice exchange a longitudinal optical (LO) phonon involve large energy changes. In particular, electron energy loss is much more efficient when effected by emission of polar optical phonons. This fact makes the electron-LO phonon interaction an important scattering mechanism for charge carriers at room temperature and for most of the polar semiconductor crystals of interest (Ridley 1993a).

This work demonstrates that radiation pressure forces can be used to impulsively move the colloid, resulting in a dipolar electric field.

Abstract:
This project developed compact, lightweight, prototype Electro-Magnetic Acoustic Transducers (EMATs) and studied guided waves for defect detection, classification, and characterization in cast iron and steel pipes. Through lab testing, design, and Finite Element Analysis (FEA), guided wave propagation and defect interactions were evaluated, and the results were employed to optimize the prototype EMATs through successive design and testing iterations. The goal of developing EMATs for robotic inspection of unpiggable pipe was successfully achieved and demonstrated not only through prototype fabr
