In this work, a recent theoretically predicted phenomenon of enhanced permittivity with electromagnetic waves using lossy materials is investigated for the analogous case of mass density and acoustic waves, which represents inertial enhancement. Star

A review of the recent advances on acoustic cloaking for airborne sound is here reported. It is shown that engineering acoustic cloaks based on transformation acoustics has a main drawback: there are no passive materials for increasing the sound spee

This work studies the absorptive properties of periodic arrays of microperforated cylindrical shells. Structures made of cylinders 3 meters height have been constructed and their reflectance and transmittance spectra are measured in open air at norma

Absorption of broadband noise by sonic crystals consisting of microperforated cylindrical shells is proposed and experimentally demonstrated. The theoretical study has been performed in the framework of multiple scattering method, where a model for t

This letter presents the design of a reduced acoustic cloak that uses a temperature gradient in order to obtain sound speeds larger than in air. The cloak consists of a circular acoustic crystal made of ten concentric layers of rigid cylinders whose

A systematic study of noise barriers based on sonic crystals made of cylinders that use recycled materials like absorbing component is reported here. The barriers consist of only three rows of perforated metal shells filled with rubber crumb. Measure

We report on different aspects of the behavior of sonic crystals with finite size. First, at wavelengths on the order of the lattice period we have observed the excitation of deaf modes, i.e., modes with symmetry orthogonal to that of the exciting be
