Acoustic properties of colloidal crystals
I. E. Psarobas, R. Sainidou, N. Stefanou +1
We present a systematic study of the frequency band structure of acoustic waves in crystals consisting of nonoverlapping solid spheres in a fluid. We consider colloidal crystals co…
Scattering and absorption of light by periodic and nearly periodic metallodielectric structures
V. Yannopapas, A. Modinos, N. Stefanou
We consider the effect of different approximations to the dielectric function of a silver sphere on the absorption of light by two-dimensional and three-dimensional periodic and no…
Optical transparency of mesoporous metals
N. Stefanou, A. Modinos, V. Yannopapas
We examine the optical properties of metals containing a periodic arrangement of nonoverlapping spherical mesopores, empty or filled with a dielectric material. We show that a slab…
Phononic crystals with planar defects
I. E. Psarobas, N. Stefanou, A. Modinos
We study the effect of planar defects in phononic crystals of spherical scatterers. It is shown that a plane of impurity spheres introduces modes of vibration of the elastic field…
Scattering of elastic waves by periodic arrays of spherical bodies
I. E. Psarobas, N. Stefanou, A. Modinos
We develop a formalism for the calculation of the frequency band structure of a phononic crystal consisting of non-overlapping elastic spheres, characterized by Lamé coefficients w…
