Abstract :
We report on a terahertz transparency in periodic arrays of metallic slits using terahertz time- domain spectroscopy. Experimental results and theoretical calculations reveal that Fabry-Perot resonance appearing in spectral region below first Rayleigh minimum strongly enhances terahertz transmission and a symmetric eigenmode inside the slits is excited under the condition of terahertz transparency.
