Abstract

A metal hole arrays terahertz filter based on surface plasmon polaritons and fabricated by aluminum slab of different holes scales have been experimentally investigated by using THz time-domain spectroscopy system from 0.1 to 2.7 THz. The experiment results indicated there is a transmission peak at 0.26 THz, approximately. The results in simulation by finite element method agree well with the experimental one for the big scale sample. The mismatch of experimental and simulated results for small scale sample can be attributed to boundary condition and insufficient periodical extension. Further, the theoretical analyses about extraordinary optical transmission and filter phenomena are also discussed.
