  • Extraordinary light transmission apparatus and method
    Patent number: 8731359
    Abstract: An optical apparatus that provides extraordinary light transmission through a sub-wavelength-sized light transmitting region of the apparatus includes a core region of dielectric material having a complex dielectric constant, ?1, surrounded by a metallic cladding material having a complex dielectric constant, ?2, wherein the core region has a maximum dimension, 2a, further wherein 2a is less than ?, where ? is the free-space wavelength of light incident on an input side of the apparatus, and further wherein |?1| is greater than 0.5|?2|, ?1 has a positive real part, and ?2 has a negative real part, whereby the incident light will be transmitted by and exit the apparatus from an output side with extraordinary transmission.
    Type: Grant
