Abstract :
We have achieved the nearly perfect transmission over 90% of random arrays that can be thought of as merely collective system of single rectangular holes with various length-to-width ratios and slits, using terahertz time domain spectroscopy. It is found that the terahertz transparency by the enhanced transmission can be experimentally realized even in the areal coverage less than 12% at the fundamental shape resonance, provided that the shape is strongly asymmetric.
