Abstract

A frequency-dependent implicit locally one-dimensional finite-difference time-domain (LOD-FDTD) method is developed for the analysis of three-dimensional (3-D) plasmonic structures. A brief formulation is given with the use of the simple trapezoidal recursive convolution technique. A gap plasmonic waveguide is analyzed to validate the 3-D LOD-FDTD. The computational time is significantly reduced to 60% of that of the traditional explicit FDTD.
