This paper presents a comprehensive review of the literature and trends on the design of
periodic microstructural composite materials including photonic crystals (PtCs), phononic …

Phononic crystals are the acoustic wave analogue of photonic crystals. Here a periodic array
of scattering inclusions located in a homogeneous host material forbids certain ranges of …

We present a full acoustic band structure calculation for periodic elastomeric solids at
different levels of deformation. We demonstrate the ability to use deformation to transform …

Acoustic band gap (ABG) materials constituted of steel hollow cylinders immersed in water
can exhibit a tunable narrow pass band (NPB) located inside their gap. We theoretically …

This paper proposes a deep-learning-based inverse design framework for a one-
dimensional, defective phononic crystal (PnC) as a narrow bandpass filter under …

Wave propagation in elastomeric materials undergoing large deformations is relevant in
numerous application areas, including nondestructive testing of materials and ultrasound …

Designing ultra-wide low-frequency bandgap acoustic metamaterial has important
application potential but is also challenging. This study proposes a systematic topology …

A sonic crystal is a finite-size periodic array composed of scatterers embedded in a
homogeneous material. It should have full band-gaps where any sound wave is not allowed …

Acoustic band gap materials, so-called phononic crystals, are introduced as a new platform
for sensing material properties in small cavities. The sensor employs specific transmission …

In this study, a multifunctional metastructure is proposed for vibration suppression by
combining a honeycomb sandwich structure and a locally resonant metastructure. To …
