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 …

Presented in this paper are study results of dispersion relationships of periodic structures
composited of concrete and rubber, from which the frequency band gap can be found. Two …

In this paper, we study the defect bands of a 1D phononic crystal consisting of aluminum (Al)
and polymethyl methacrylate (PMMA) layers with a dielectric elastomer (DE) defect layer …

Lightweight metastructures are designed consisting of prismatic tensegrity building blocks
which have excellent strength-to-weight ratio and also enable unique compression-torsion …

We propose a new type of phononic crystal (PnC) composed of a periodic alternation of
circular cavity sandwich plates. In the low-frequency regime, the crystal can modulate the …

A new type of concrete, named metaconcrete, has been developed for the attenuation of
shock waves induced by dynamic excitation. Inspired by the metamaterials used for the …

In this work, an innovative vibration energy harvester is designed by using the point defect
effect of two-dimensional (2D) magneto-elastic phononic crystals (PCs) and the piezoelectric …

The band gaps of a laminated piezoelectric/piezomagnetic phononic crystal with graded
interlayer are studied in this paper. First, the transfer matrix method and the Bloch theorem …

The flexible manipulation of elastic waves that exhibit abundant polarization characteristics
in solid structures can be realized through ingenious microstructure design, thus …
