About the ebook: This booklet is the 1st finished evaluation on acoustic metamaterials; novel fabrics that can control sound waves in fantastic methods, which come with collimation, focusing, cloaking, sonic screening and remarkable transmission. It covers either experimental and theoretical facets of acoustic and elastic waves propagating in dependent composites, with a spotlight on powerful houses linked to damaging refraction, lensing and cloaking. so much comparable books within the box deal with electromagnetic metamaterials and concentrate on numerical equipment, and little (or no) experimental part. every one bankruptcy can be authored by way of an stated professional, among the themes coated may be experimental effects on non-destructive imaging, cloaking via floor water waves, flexural waves in skinny plates. purposes in scientific ultrasound imaging and modeling of metamaterials can be emphasised too. The publication can function a reference for researchers who desire to construct a pretty good beginning of wave propagation during this category of novel materials.

We report in Fig. 10 finite element computations for a periodic cell of side length d with a double C-shaped void. 03d. 5 for the lowest value point on the second dispersion curve on Fig. 10 occurring at the A point (where the Bloch vector k vanishes). This provides us with an estimate of the upper-edge frequency of the first gap. We note that if we take V (0) = 0 instead of V (0) = meas(Ξ )/meas(Y \ Ω) (cf. 39 for the lower-edge of the first gap (occurring at the C point when k = (π, π)). The associated eigenfield is strongly localized inside the SRR, as can be seen in Fig.
