Abstract

We numerically study nanoparticle dimer (two closely-spaced nanoparticles) with the aim to resolve gap plasmon mode using finite-difference time-domain (FDTD) method. Our semi-conformal meshing based on transformation optics principles allows for accurate accounting of nanoparticle gaps and other curved shapes. We calculate surface plasmon amplification by stimulated emission of radiation (SPASER) in the dimer modes using Bloch equations.
