The use of the ultrasonic wave technology was expected as one of important technologies in health monitoring of composite materials and/or structures. However, the propagation of ultrasonic wave becomes very complicated for polymer based composite materials due to reflection, transmission, dispersion and...
The primary aim of this paper is to undertake an analytical investigation of the dispersion and damping behaviours of Love-type waves propagation in a porous piezoelectric layer sandwiched between a dissipative transversely isotropic poroelastic layer of finite thickness and a homogeneous transversely ...
This paper studies wave propagation in a periodic parallel-plate waveguide with equilateral triangular holes. A mode-matching method is implemented to analyze the dispersion diagram of the structure possessing glide and mirror symmetries. Both structures present an unexpected high degree of isotropy, desp...
1. Structure adapted to propagate an electromagnetic wave, comprising: at least one conductive member, and an adjacent dielectric material distributed in a wave propagation direction, through which said wave passes, said dielectric material exhibiting non-linear conductivity such that it is substantially...
The ability to slow down wave propagation in materials has attracted significant research interest. A successful solution will give rise to manageable enhanced wave–matter interaction, freewheeling phase engineering and spatial compression of wave signals. The existing methods are typically associated with...
influenced by electric and magnetic fields. The key contribution of the current work is demonstrating the influence of sliding interface, thickness of the piezomagnetic layer, thickness ratio, external magnetic field, balancing force, and microscale length parameter on the shear wave propagation. The ...
In practical engineering, noise and impact hazards are pervasive, indicating the pressing demand for materials that can absorb both sound and stress wave energy simultaneously. However, the rational design of such multifunctional materials remains a chal
The study of wave propagation in the periodic nano-waveguides is of importance to advance the development of energy and wave controlling systems. In this paper, firstly, the element discretization of nano structures is introduced based on the second strain gradient theory. The displacement field is...
A two-dimensional lattice dynamics model for a viscoelastic composite reinforced with two sets of orthogonally interlocking fibers is given, and the propagation of plane harmonic waves in such a medium is investigated. The composite considered consists of two sets of orthogonal equivalent elastic fibers...
