Terahertz wave transmission through the subwavelength metallic stripe arrays is investigated by terahertz time domain spectroscopy. A number of factors, including the shape of the metal structures and the periodicity of the arrays, are found to influence terahertz transmission properties. The numerical simulations based on FDTD method show a good agreement with experimental results. The physical origin of impacting transmission is analyzed. The obtained results provide a useful reference for the fabrication of THz band-stop filters.
