Abstract :
A novel system based on terahertz time domain spectroscopy was established. On this system, we experimentally studied both the reflection and transmission properties of the deep zero-order grating with subwavelength slits. Enhanced transmission spectra were observed, which were strongly dependent on the geometry of the sample and complementary to the reflection spectra. The experimental results agree well with the theoretical analysis.
