Special Issue Information

Dear Colleagues,

The study of acoustic and electromagnetic metamaterials has flourished since the beginning of the 21st century. Their fascinating properties arise from the possibility of designing and realizing artificial structures with negative values of their effective parameters. As a result, promising applications such as negative refraction in acoustics as well in electromagnetism and the potential for all kinds of devices based on it became a true possibility, no longer confined to mere speculations in articles and textbooks.

Coordinate transformations have been applied to a wide range of classical waves and have led to the proposal of acoustic, mechanical, thermal, and electromagnetic cloaks. Furthermore, the possibility of tailoring the effective parameters has led to other exciting applications, including the demonstration of gradient index lenses for acoustic and mechanical waves. The acoustic and EM analogues of black holes are also promising devices that are of current interest in the field of metamaterials. The design of metasurfaces to control the transmission and reflective properties of impinging waves has become a hot topic in the last few years. For the last several decades, there have been designs for noise barriers based on phononic crystals, but only recently have we experienced a twist thanks to the introduction of metamaterials, allowing for the design of barriers with thicknesses much smaller than the wavelength of the impinging noise. More recently, the rapid development of additive manufacturing (3D printing) has enabled the fabrication of metamaterials devices that are impractical or impossible to make using traditional techniques.

The field of metamaterials is advancing into the development of new kinds of devices, poised to become commercial products in the coming years. It is our pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

An acoustic metamaterial superlattice is used for the spatial and spectral deconvolution of a broadband acoustic pulse into narrowband signals with different central frequencies. The operating frequency range is located on the second transmission band of the superlattice. The decomposition of the broadband pulse was achieved by the frequency-dependent refraction angle in the superlattice. The refracted angle within the acoustic superlattice was larger at higher operating frequency and verified by numerical calculated and experimental mapped sound fields between the layers. The spatial dispersion and the spectral decomposition of a broadband pulse were studied using lateral position-dependent frequency spectra experimentally with and without the superlattice structure along the direction of the propagating acoustic wave. In the absence of the superlattice, the acoustic propagation was influenced by the usual divergence of the beam, and the frequency spectrum was unaffected. The decomposition of the broadband wave in the superlattice’s presence was measured by two-dimensional spatial mapping of the acoustic spectra along the superlattice’s in-plane direction to characterize the propagation of the beam through the crystal. About 80% of the frequency range of the second transmission band showed exceptional performance on decomposition. Full article
