Impact of the inherent periodic structure on the effective medium description of left-handed and related meta-materials
Th. Koschny, P. Markos, E. N. Economou +3
We study the frequency dependence of the effective electromagnetic parameters of left-handed and related meta-materials of the split ring resonator and wire type. We show that the…
Negative refraction and superlensing in a 2D photonic crystal structure
R. Moussa, S. Foteinopoulou, Lei Zhang +4
We experimentally and theoretically studied a new left-handed (LH) structure based on a photonic crystal (PC) with a negative refractive index. The structure consists of triangular…
Intensity distribution of scalar waves propagating in random media
P. Markos, C. M. Soukoulis
Transmission of the scalar field through the random medium, represented by the system of randomly distributed dielectric cylinders is calculated numerically. System is mapped to th…
Electric coupling to the magnetic resonance of split ring resonators
N. Katsarakis, T. Koschny, M. Kafesaki +2
We study both theoretically and experimentally the transmission properties of a lattice of split ring resonators (SRRs) for different electromagnetic (EM) field polarizations and p…
Effective medium theory of left-handed materials
T. Koschny, M. Kafesaki, E. N. Economou +1
We analyze the transmission and reflection data obtained through transfer matrix calculations on metamaterials of finite lengths, to determine their effective permittivity and perm…
EM wave propagation in two-dimensional photonic crystals: a study of anomalous refractive effects
S. Foteinopoulou, C. M. Soukoulis
We systematically study a collection of refractive phenomena that can possibly occur at the interface of a two-dimensional photonic crystal, with the use of the wave vector diagram…
