      N-to-Δ electromagnetic-transition form factors from lattice QCD 

      Alexandrou, Constantia; De Forcrand, P.; Neff, H.; Negele, J. W.; Schroers, W.; Tsapalis, Antonios (2005)
      The magnetic dipole (M1), the electric quadrupole (E2), and the Coulomb quadrupole (C2) amplitudes for γN → Δ are calculated in quenched lattice QCD. Using a new method, which combines an optimal choice of interpolating ...

      Negative-refractive-index transmission-line metamaterials and enabling electromagnetic applications 

      Eleftheriades, G. V.; Grbic, A.; Antoniades, Marcos A. (2004)
      The negative-refractive-index (NRI) metamaterials, for which the permittivity and permeability are simultaneously negative, were discussed. The results for two RF/Microwave devices and structures, based on transmission-line ...

      Prediction of rainfall rate based on weather radar measurements 

      Christodoulou, Christodoulos I.; Michaelides, Silas C.; Gabella, M.; Pattichis, Constantinos S. (2004)
      Weather radars are used to measure the electromagnetic radiation backscattered by cloud raindrops. Clouds that backscatter more electromagnetic radiation consist of larger droplets of rain and therefore they produce more ...

      Tunable excitons in gated graphene systems 

      Djotyan, Anahit P.; Avetisyan, A. A.; Moulopoulos, Konstantinos (SPIE, 2017)
      We develop a microscopic theory of a strong electromagnetic radiation interaction with bilayer graphene where an energy gap is opened by a static electric field perpendicular to graphene planes. We show that an adiabatic ...
