Strong influence of periodicity on extraordinary transmission through periodic arrays of subwavelength holes

摘要

Quadrate hole array is explored to study the influence of unsymmetrical periodicity on extraordinary optical transmission through periodic arrays of subwavelength holes. It is found that the transmission efficiency of light and the ratio between transmission efficiencies of horizontal and vertical polarized light can be continuously tuned by rotating the quadrate hole array. A simple theoretical model is also given.
