A new seismic isolation foundation called the periodic foundation is proposed, which can be
described as a three-dimensional typical cell consisting of a high density core, a soft coating …

This is a comprehensive theoretical survey of acoustic wave propagation in layered
materials including elastic, viscoelastic and piezoelectric layers. The phonon modes are …

A novel small size multi-band gaps phononic crystal (hPC) composed of the periodic
plumbum and aluminum mass has been investigated in this paper, we calculated the …

It is known that the transmission spectrum of the so-called locally resonant phononic crystal
can exhibit absolute sharp dips in the sonic frequency range due to the resonance scattering …

The band gap of one dimensional (1D) phononic crystal with viscoelastic host material is
studied in this paper. The standard solid model is used to simulate the viscoelastic behavior …

Low-frequency vibrations, such as earthquakes and wind loads, may negatively affect the
proper operation of buildings and bridges and even lead to structural failure. Even though, in …

This work presents a comprehensive mathematical treatment of phononic crystals (PCs)
which comprise a finite lattice of repeated polyatomic unit cells. Wave dispersion in …

Recently, sensor technology has attracted great attention in many fields due to its
importance in many engineering applications. In the present work, we introduce a study …

A new type of modified concrete, termed metaconcrete, has been shown to exhibit trapping
of wave energy and a reduction in mortar stress when subjected to dynamic loading …

This research presented a comprehensive study of a one-dimensional (1D) porous silicon
phononic crystal design as a novel fluidic sensor. The proposed sensor is designed to detect …
