Cloaking by anomalous localized resonance
WebA review of anomalous resonance, its associated cloaking, and superlensing Ross C. McPhedran 1 and Graeme W. Milton 2 ... By contrast, anomalous localized resonance … WebIn order to explain cloaking by anomalous localized resonance (CALR) which is the subject of this paper, it seems most convenient to begin by stating precisely the mathematical problem. Let D and Ω be bounded domains in Wl (id = 2,3) such that D C il so that D is the core and Ω is the shell (see Figure 1).

WebOct 4, 2015 · We also show on ellipses that cloaking by anomalous localized resonance takes place at accumulation points of eigenvalues. We first investigate spectral properties of the Neumann–Poincaré (NP) operator for the Lamé system of elasto-statics. We show that the elasto-static NP operator can be symmetrized in the same way as that for the Laplace ... WebFeb 27, 2024 · Finally, the ALR has a practical feature that it can induce the invisibility cloaking effect. If ALR occurs, then both the underlying material structure and the source are invisible with respect to observations outside a certain region. This is referred to as cloaking due to anomalous localized resonance (CALR) in the literature.
WebJun 8, 2013 · Cloaking by anomalous localized resonance (CALR) may occur when the support of the source, or part of it, lies in the anomalously resonant region. Physically the … WebRegions of anomalous localized resonance, such as occurring near superlenses, are shown to lead to cloaking effects. This occurs when the resonant field generated by a …
WebAs a consequence, we prove that cloaking by anomalous localized resonance does not occur on three-dimensional strictly convex smooth domains. We then look into the surface localization of the plasmons on the Clifford torus by numerical computations. The Clifford torus is taken as an example of nonconvex surfaces. WebApr 30, 2024 · We consider the anomalous localized resonance induced by negative elastic metamaterials and its application in invisibility cloaking. We survey the recent mathematical developments in the literature and discuss two mathematical strategies that have been developed for tackling this peculiar resonance phenomenon.
WebMar 1, 2016 · We show that the resonance at the essential spectrum (on ellipses) is the anomalous localized resonance which was first discovered on a concentric core-shell structure in [21]. We also show that cloaking by anomalous localized resonance takes place on ellipses.
