Abstract
The SPPs propagation on curved metal-dielectric interface is simulated by FDTD(finite-difference time-domain) method. The propagation loss, the transmittance and the reflection coefficients of SPPs on curved metal-dielectric interface with different radius of curvature is presented. The results shows the radiation loss is the key factor for the SPPs propagation when the propagation area is the same order as the wavelength, and the reflection coefficient is so small that it is ignorable. The critical situation when the radius is zero is also analyzed and the reflection coefficient is much larger than the former situation; for the transmittance, different electronic field components play different roles.
