Comparison of transmission resonance phenomena through small coupling apertures between two kinds of transmission resonance structures

Abstract

We deal with two kinds of transmission resonance structures whose transmission areas are the same to each other as 3λ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /4π. One is a ridged aperture structure and the other is the structure employing aperture - to - cavity - to - aperture system. We expect the two structures to be useful for various applications such as near-field optical probes, compact optical data storage, and nano-lithography.
