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, &#x2208;, surrounded by a metallic cladding material having a complex dielectric constant, &#x2208;, wherein the core region has a maximum dimension, 2a, further wherein 2a is less than &#x3bb;, where &#x3bb; is the free-space wavelength of light incident on an input side of the apparatus, and further wherein |&#x2208;| is greater than 0.5|&#x2208;|, &#x2208;has a positive real part, and &#x2208;has a negative real part, whereby the incident light will be transmitted by and exit the apparatus from an output side with extraordinary transmission.
