Application of generalized method of eigenoscillations to problems of nanoplasmonics
This work addresses computational efficiency in nanoplasmonics for researchers modeling nanoparticle resonances, but the approach is incremental and limited to axisymmetric geometries.
The authors apply a generalized eigenoscillation method to model resonant effects in metallic nanoparticles, proposing an algorithm to compute only the resonant eigenoscillation without calculating all higher modes. Numerical results for bodies of revolution are presented.
A version of generalized eigenoscillation method is applied to the problem about resonant effects in metallic nanoparticles. An approach is proposed, that permits to avoid calculating all higher eigenoscillations except the resonant one. An algorithm for determination of the resonant eigenoscillation, based on the Galerkin procedure, is described in details for the case of bodies of revolution. Model numerical results are presented.
