  • Angle-independent microwave absorption by ultrathin microcavity arrays 

    Brown, James R.; Hibbins, Alastair P.; Lockyear, Matthew J.; Lawrence, Christopher R.; Sambles, J. Roy (American Institute of Physics, 2008)
    The resonant absorption of microwave radiation by thin, two-dimensional microcavity arrays has been studied. Resonant modes associated with these structures, formed from copper-clad FR4 laminates, exhibit both an azimuthal ...
  • Microwave resonances of ultrathin hexagonally-symmetric microcavity arrays 

    Brown, James R.; Hibbins, Alastair P.; Lawrence, Christopher R.; Lockyear, Matthew J.; Sambles, J. Roy (American Institute of Physics, 2012)
    A metamaterial surface formed by three slot gratings at 60° to each other has two possible high-symmetry arrangements. One forms equilateral triangular metal patches, the other a combination of hexagons and small equilateral ...
  • The Microwave Response Of Ultra Thin Microcavity Arrays 

    Brown, James R. (University of ExeterSchool of Physics, 2010-04-14)
    The ability to understand and control the propagation of electromagnetic radiation underpins a vast array of modern technologies, including: communication, navigation and information technology. Therefore, there has been ...
  • Squeezing millimeter waves into microns 

    Hibbins, Alastair P.; Sambles, J. Roy; Lawrence, Christopher R.; Brown, James R. (American Physical Society, 2004)
    Microstructured metallic devices will play a vital role in the continuing search to manipulate the passage of electromagnetic radiation relevant to optical, microwave, and communication technologies. Here, we investigate ...
