We design a magneto-electro-elastic piezoelectric phononic crystal (MPPC) using one-dimensional superlattice (with 3m point group) and split-ring resonators. The effect of the resonators is to enhance superlattices. This will create elastic anomalies generate band gaps. These are first proposed theoretically. calculate transmission function MPPC through Transfer Matrix Method crystal. By functi...

In recent years, the idea of controlling phonon thermal transport coherently using phononic crystals has been introduced. Here, we extend our previous numerical studies of ballistic low-temperature heat transport in two-dimensional hole-array phononic crystals, and concentrate on the effect of the lattice periodicity. We find that thermal conductance can be either enhanced or reduced by large f...

Electron material waves cannot permeate a periodic atomic lattice at each energy or frequency. There exists forbidden gap due to the periodicity of atoms. In analogy, acoustic penetrate phononic sonic crystal A two-dimensional consists cylinders. The is adjusted according wavelength sound. Depending on frequency, there exist “allowed” bands with propagation as well “forbidden” band without corr...

A mono-channel waveguide with alternate hollow pillars of different radius to passively select and reject particular frequencies for filtering applications are numerically simulated based on the Finite Element Method (FEM). The waves guided while can be filtered according pillar inner as its waveguiding mechanism. computations dispersion relation, transmission coefficient stress displacement pr...

This work studies the propagation of mechanical waves through lattices that form moir\'e patterns. These structures are not periodic, and their analysis generally requires special methods, most which based on theory quasiperiodic infinite systems, therefore suitable for finite manufactured structures. To attain a deeper understanding underlying physics patterns, authors study these complex usin...
