Abstract :
To study transmission resonances in periodic metal arrays of slits, we used the THz time domain spectroscopy system wih high power THz sources. The resonance peaks of zero-order transmission spectra are attributed to the combined effects of Fabry -Perot and surface plasmon resonances. Fabry-Perot effect enhances the transmission when two resonances cross but does not alter the surface plasmon peak positions. These results are in agreement with theoretical calculations.
