  • Phase resonances on metal gratings of identical, equally spaced alternately tapered slits 

    Rance, Helen J.; Hamilton, Oliver K.; Sambles, J. Roy; Hibbins, Alastair P. (American Institute of Physics, 2009)
    Phase resonances are observed in the microwave response of metal transmission gratings comprised of identical but alternately orientated tapered slits. Despite each slit having identical dimensions, and being equally spaced ...
  • Polarization conversion from a thin cavity array in the microwave regime 

    Tremain, B.; Rance, Helen J.; Hibbins, Alastair P.; Sambles, J. Roy (Nature Publishing Group:, 2015-03-23)
    Linearly polarized microwave radiation is shown to have its plane of polarization converted to the orthogonal state upon reflection from an ultrathin (λ/25) cavity array. The structure benefits from an uncomplicated design ...
  • Structurally dictated anisotropic "designer surface plasmons" 

    Rance, Helen J.; Hooper, Ian R.; Hibbins, Alastair P.; Sambles, J. Roy (American Institute of Physics, 2011)
    The concept of pseudo-plasmonic surfaces at microwave frequencies is extended to include structures with a high degree of surface anisotropy. The experimental sample is fabricated by patterning a metal with a rectangular ...
  • Surface plasmons on zig-zag gratings 

    Constant, Thomas J.; Taphouse, T. S.; Rance, Helen J.; Kitson S. C.; Hibbins, Alastair P.; Sambles, J. Roy (Optical Society of America, 2012-10-04)
