In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

Phononic crystals have been proposed about two decades ago and some important
characteristics such as acoustic band structure and negative refraction have stimulated …

Phononic crystal is a type of artificial heterogeneous material constituted by a periodic
repetition of cells. This characteristic provides a possible solution to the accurate …

Existing techniques in correlation spectroscopy, such as coda wave interferometry and
diffusing acoustic wave spectroscopy, determine the average motion of scatterers or change …

Acoustic metamaterials (AMMs) are a type of artificial materials that make use of appropriate
structural designs and exhibit exotic properties not found in natural materials, such as …

The character of wave transport through a strongly scattering medium, excited by a pulsed
