    Hibbins, Alastair P.; Sambles, J. Roy; Lawrence, Christopher R.; Robinson, Donna M. (American Institute of Physics, 2001)

    Suckling, James R.; Sambles, J. Roy; Lawrence, Christopher R. (American Physical Society, 2005)
    A slit in a thick metal plate that is extremely subwavelength will not transmit microwaves polarized parallel to it. It is shown here that cuts perpendicular to the slit allow parallel polarized radiation to resonantly ...

    Yang, Fuzi; Sambles, J. Roy (American Physical Society, 2002)
    Strong resonant transmission of microwave radiation through a very narrow (much less than the radiation wavelength) metallic slit is recorded. The results show that a set of resonant self-coupled surface plasmons are excited ...
