Paper Abstract

In this paper, we investigated the electric field profiles and phase distribution at the metal interfaces of the structure, and then analyzed their dependence on the groove depth and distance between slit and grooves though finite-difference time-domain (FDTD) simulation. Calculated results show that variant groove depth generates phase difference periodically, which indicates the existence of standing wave in the groove. The results also show that the phase of the emission at each groove is proportional to the distance travelled by the surface wave in one period. Based on these facts, a simple process of the transmission model is illuminated.
