  • Anomalous retroreflection from nanoporous materials as backscattering by `dark' and `bright' modes 
    SERGENTU, V. V.; PRISLOPSKI, S. Ya.; MONAICO, E. V.; URSAKI, V. V.; GAPONENKO, S. V.; TIGINYANU, I. M. (IOP Publishing, 2016)
    In this paper the mechanisms of previously experimentally observed anomalous retroreflection in a strongly absorbing nanostructured medium are explained by using ‘dark’ and ‘bright’ modes. The observed regularities are ...
  • Anomalous retroreflection from strongly absorbing nanoporous semiconductors 
    PRISLOPSKI, S. Ya.; NAUMENKO, E. K.; TIGINYANU, I. M.; GHIMPU, L.; MONAICO, E.; SIRBU, L.; GAPONENKO, S. V. (Optical Society of America, 2011)
    Pronounced retroreflection behavior is reported for a fishnet nanoporous strongly absorbing semiconductor material. Retroreflection features a half-cone about 0.35 rad along with diffusive specular reflection for all angles ...
  • “Dark” modes backscattering as possible rationale for anomalous retroreflection from strongly absorbing porous nanostructures 
    SERGENTU, V. V.; URSAKI, V.; MONAICO, Ed.; TIGINYANU, I. M.; PRISLOPSKI, S. Ya.; GAPONENKO, S. V. (World Scientific, 2017)
    The previously discovered anomalous retroreflection in a strongly absorbing nanostructured medium is explained by using “dark” and “bright” modes. The consideration provides rationale not only for the retroreflection itself ...
  • Polarized Retroreflection from Nanoporous III–V Semiconductors 
    PRISLOPSKI, S. Ya.; GAPONENKO, S. V.; MONAICO, E.; SERGENTU, V. V.; TIGINYANU, I. M. (Springer Nature Switzerland, 2018)
    Retroreflected light with strong linear polarization coinciding with that of the incident beams is detected from strongly absorbing nanoporous III–V semiconductors. Because of high polarization of retroreflected waves we ...
  • Retroreflection from disordered porous semiconductors 
    PRISLOPSKI, S.; TIGINYANU, I. M.; GHIMPU, L.; MONAICO, E.; SIRBU, L.; ZHUKOVSKY, S. V.; GAPONENKO, S. V. (IEEE, 2011)
    Prominent retroreflection is experimentally observed in disordered porous InP membranes. It is believed to be the result of an interplay between Fresnel-like and Bragg-like reflection for different components of an impinging ...
  • Retroreflection of light from nanoporous InP: correlation with high absorption 
    PRISLOPSKI, S. Ya.; TIGINYANU, I. M.; GHIMPU, L.; MONAICO, E.; SIRBU, L.; GAPONENKO, S. V. (Springer Nature Switzerland, 2014)
    Pronounced retroreflection behavior is reported for a fishnet nanoporous strongly absorbing semiconductor material. Retroreflection appears along with diffusive specular reflection for all angles of incidence for light ...
