In this paper, we numerically and experimentally demonstrate the existence of complete
band gaps and resonances in a plate with a periodic stubbed surface. Numerical results …

We present theoretically a type of one-dimensional (1D) structured ultrasonic metamaterial
that exhibits a forbidden band where both the effective dynamic density and bulk modulus …

Flexural vibration in a pipe system conveying fluid is studied. The pipe is designed using the
idea of the phononic crystals. Using the transfer matrix method, the complex band structure …

The field of engineered materials with designed properties is expected to continue to grow in
the future, and metamaterials are instrumental in allowing this freedom of design …

The authors demonstrate that a class of ultrasonic metamaterial, which is composed of
subwavelength resonant units built up by parallel-coupled Helmholtz resonators with …

Using a periodic expansion by means of the Bloch theorem, the flexural vibration band gaps
are studied in a thin plate with two-dimensional ternary locally resonant structures, ie a thin …

The propagation characteristics of flexural waves in a two-dimensional (2D) periodic grid-
like structure are analysed with the plane wave expansion method to yield phase constant …

Based on Mindlin's piezoelectric plate theory and the plane wave expansion method, a
formulation is proposed to study the frequency band gaps and dispersion relations of the …

The phonon–polariton behaviors of two-dimensional piezoelectric phononic crystals (PPCs)
were studied using the plane wave expansion method. The governing equations combine …

We derive the general dispersion and dissipation relations for a one-dimensional
viscoelastic lattice, demonstrate the relevance of these relations to viscoelastic fracture and …
