Optical photonic crystals fabricated from colloidal systems
G. Subramania, K. Constant, R. Biswas +2
Photonic crystals of close-packed arrays of air spheres in a dielectric background of titania have been fabricated with a novel ceramic technique. Unlike previous methods, ordering…
Band-gap tuning in 2D spatiotemporal phononic crystals
D. Psiachos, M. M. Sigalas
We investigate the effect of small spatiotemporal modulations in subwavelength-dimensioned phononic crystals with large band gaps, on the frequency spectrum for elastic waves polar…
Tailoring one-dimensional layered metamaterials to achieve unidirectional transmission and reflection
D. Psiachos, M. M. Sigalas
We investigate elastic-wave propagation in a spatially-dispersive multilayered, totally passive metamaterial system. At oblique incidence a longitudinal (acoustic) wave can convert…
Acoustic response in a a one-dimensional layered pseudo-Hermitian metamaterial containing defects
D. Psiachos, M. M. Sigalas
Using transfer-matrix methods, we investigate the response of a multilayered metamaterial system containing defects to an incident acoustic plane wave at normal or oblique incidenc…
Thermal expansion and the equation of state of Ir and Rh
M. I. Katsnelson, M. Sigalas, A. V. Trefilov +1
The simplest anharmonic characteristics of Ir and Rh are discussed in the framework of a previously developed simple pseudopotential model which describes the elastic moduli, phono…
