Using the framework of transformation optics, this paper presents a detailed analysis of a non-singular square cloak for acoustic, out-of-plane shear elastic, and electromagnetic waves. The generating map is examined in detail and linked to the mater

Transmission and Anderson localization in dispersive metamaterials

Autor: Asatryan, AA, Botten, LC, Byrne, MA, Freilikher, VD, Gredeskul, SA, Shadrivov, IV, McPhedran, RC, Kivshar, YS

Comprehensive theoretical and numerical studies of the effects of dispersion and absorption on the Anderson localization of classical waves in weakly disordered, one-dimensional stacks composed of dispersive metamaterials and normal materials are pre

International audience; We consider thin lamellar and cylinder gratings, composed of silicon carbide and air, and investigate the conditions under which they can totally absorb an incident plane wave, for both p and s polarizations. We also consider

Suppression of Anderson localization in disordered metamaterials

Autor: Asatryan, AA, Botten, LC, Byrne, MA, Freilikher, VD, Gredeskul, SA, Shadrivov, IV, McPhedran, RC, Kivshar, YS

We study wave propagation in mixed, 1D disordered stacks of alternating right- and left-handed layers and reveal that the introduction of metamaterials substantially suppresses Anderson localization. At long wavelengths, the localization length in mi

Generalisation of the transfer matrix formulation of the theory of electron and photon conductance

Autor: Botten, LC, Asatryan, AA, Nicorovici, NA, McPhedran, RC, Martijn de Sterke, C

The usual technique for calculating the mesoscopic conductance of materials is based on Pichard's transfer matrix method [J.L. Pichard, Thesis, University of Paris, Orsay, 1984]. The essential ideas of the theory of conductance for electronic systems
