Abstract :
We demonstrated some imaging applications of THz radiations, such as non-destructive detection of illicit drugs in a envelope. We also demonstrated a high sensitive terahertz sensing application by using a resonant transmission phenomenon of metal hole array which is attributed to a excitation of surface waves.
