Abstract

We studied the effect of truncation on the plasmonic resonance of triangular nanoprisms. Perfect Ag triangular prisms and Ag truncated triangular prisms have been designed and simulated using finite-difference time-domain (FDTD) simulation technique. Simulation results show that the increase of the truncations depth in triangular nanoprisms causes a resonance blue shift. However, for the case of truncation depth of up to 15 nm, the number of truncated corners has no effect on the position of the peak or the strength.
