  • Resonant Transmission of Microwaves through a Narrow Metallic Slit 

    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 ...
