  • Direct observation of negative-index microwave surface waves. 

    Dockrey, JA; Horsley, SA; Hooper, Ian R.; Sambles, JR; Hibbins, Alastair P. (Nature Publishing Group: Open Access Journals - Option C, 2016-02-23)
    Waves propagating in a negative-index material have wave-front propagation (wavevector, k) opposite in direction to that of energy flow (Poynting vector, S). Here we present an experimental realisation at microwave frequencies ...
  • Fluid Mobility over Corrugated Surfaces in the Stokes Regime 

    Shelley, S; Smith, JD; Hibbins, AP; Sambles, JR; Horsley, SAR (American Institute of Physics (AIP), 2016-08-01)
    An exact solution is found for laminar fluid flow along the grooves of a family of surfaces whose shape is given by the Lambert W-function. This simple solution allows for the slip length in the direction parallel to the ...
  • Fluid Mobility over Corrugated Surfaces in the Stokes Regime - datasets 

    Shelley, S; Smith, JD; Hibbins, AP; Sambles, JR; Horsley, SAR
  • Omnidirectional surface wave cloak using an isotropic homogeneous dielectric coating 

    Mitchell-Thomas, RC; Quevedo-Teruel, O; Sambles, JR; Hibbins, AP (University of Exeter, 2016-07-21)
    Datasets for Fig 4
  • Omnidirectional surface wave cloak using an isotropic homogeneous dielectric coating 

    Mitchell-Thomas, RC; Quevedo-Teruel, O; Sambles, JR; Hibbins, AP (Nature Publishing Group, 2016)
    The field of transformation optics owes a lot of its fame to the concept of cloaking. While some experimental progress has been made towards free-space cloaking in three dimensions, the material properties required are ...
  • Thin structured rigid body for acoustic absorption 

    Starkey, TA; Smith, JD; Hibbins, AP; Sambles, JR; Rance, HJ (AIP Publishing, 2017-01-23)
    We present a thin acoustic metamaterial absorber, comprised of only rigid metal and air, that gives rise to near unity absorption of airborne sound on resonance. This simple, easily fabricated, robust structure comprising ...
  • Topological Modes in One Dimensional Solids and Photonic Crystals 

    Atherton, TJ; Butler, CAM; Taylor, MC; Hooper, Ian R.; Hibbins, Alastair P.; Sambles, JR; Mathur, H (American Physical Society, 2016-03-02)
    It is shown theoretically that a one-dimensional crystal with time reversal symmetry is characterized by a Z_{2} topological invariant that predicts the existence or otherwise of edge states. This is confirmed experimentally ...
