Forces and Lattice Relaxations Calculated by a Full-Potential KKR-Green's Function Method (2007)
T. Korhonen, N. Papanikolaou, R. Zeller, P. H. Dederichs, N. Stefanou
In this review we demonstrate that a recently developed full-potential KKR-Green's function method allows an efficient calculation of forces and lattice relaxations in transition metals. The...

Observation and tuning of hypersonic bandgaps in colloidal crystals (2006)
Cheng, W., Wang, J. J., Jonas, Ulrich, Fytas, G., Stefanou, N.
Acoustic properties of colloidal crystals (2001)
Psarobas, I. E., Sainidou, R., Stefanou, N., Modinos, A.
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 consisting of...
On wave propagation in inhomogeneous systems (2001)
Modinos, A., Stefanou, N., Psarobas, I. E., Yannopapas, V.
We present a theory of electron, electromagnetic, and elastic wave propagation in systems consisting of non-overlapping scatterers in a host medium. The theory provides a framework for a unified...
Optical transparency of mesoporous metals (2001)
Stefanou, N., Modinos, A., Yannopapas, V.
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 of such a porous...
Yannopapas, V., Modinos, A., Stefanou, N.
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 non-periodic arrays...
Phononic crystals with planar defects (2000)
Psarobas, I. E., Stefanou, N., Modinos, A.
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 localized on this...
Scattering of elastic waves by periodic arrays of spherical bodies (2000)
Psarobas, I. E., Stefanou, N., Modinos, A.
We develop a formalism for the calculation of the frequency band structure of a phononic crystal consisting of non-overlapping elastic spheres, characterized by Lam\'e coefficients which may be...
Light scattering by non-spherical plasma-particles (1992)
Karathanos, V., Modinos, A., Stefanou, N.
A point matching method is applied to the problem of light scattering by non-spherical bodies. The electromagnetic field is expanded into a series of spherical waves which include all multipole terms...
