Plasmonic resonances of nanowires with periodically corrugated cross sections

Your library or personal account may give you access

Abstract

For periodically corrugated nanowire cross sections, such that the polar-angle dependence of the radius is r=r0[1+uNcos(Nφ)], we calculate both the resonant values of metal permittivity ε and the corresponding plasmonic eigenfunctions. For sufficiently small perturbation amplitudes, NuN1, these fundamental characteristics admit full-scale analytical analysis revealing nontrivial plasmonic properties. For NuN>1, the analytical analysis is supplemented by numerical simulations; they show nonlinearly growing redshifts of the main plasmonic resonances with increasing modulation periodicity N and the amplitude uN.
