Investigation of surface plasmon resonance of nanoparticles using volume integral equation

Abstract

This paper investigates the interactions between incident electromagnetic wave and nanoparticles, especially metallic nanoparticles. The scattering of nanoparticles is characterized by using volume integral equation. By considering the total electric field, i.e. the sum of incident fields and the radiated fields by equivalent electric volume currents, the volume integral equation can be established within the scatterers. The resultant volume integral equation is discretized using appropriate basis functions and is solved numerically using a matrix solver. Numerical results are presented to demonstrate the application of volume integral equation to analyze the plasmon resonance.
