  • Analytical investigations of ground modifications assisting the detection of buried object 
    Valagiannopoulos, Constantinos; Tsitsas, Nikolaos L.; Sihvola, Ari H. (Nazarbayev University School of Science and Technology, 2016-08-18)
    A ground-penetrating radar (GPR) antenna excites a perfectly electric conducting inclusion buried inside the ground. The scattering problem is solved semi-analytically via integral equation techniques. The permittivity and ...
  • Anomalous reflection of visible light by all-dielectric gradient metasurfaces 
    Tsitsas, Nikolaos L.; Valagiannopoulos, Constantinos (Journal of the Optical Society of America B, 2017-03-15)
    Plane wave scattering by a planar metasurface composed of two periodically alternating rectangular dielectric rods is considered. A rigorous integral equation methodology is employed for the analysis and the accurate ...
