Simulation of Light Scattering with Different Wavelengths from a Plasmonic Nanowire Using Surface Integral Equations Method

In this paper, the surface integral equation (SIE) method that is based on Stratton-Chu integral equations isused to simulate light scattering from a plasmonic nanowire. First, the surface integrals which are in the form ofFredholm’s equation of second kind are obtained. Then, the field distribution around a plasmonic nanowire illuminatedby various wavelengths of light is numerically calculated using a trapezoidal integration scheme. It is observed that forwavelengths much larger than the radius of the nanowire, localized surface plasmon polariton resonance occurs, whereas,at wavelengths comparable to the radius the propagating surface plasmon polariton as well as diffraction pattern appears.For wavelengths much smaller than the radius the field distribution tends to be the geometrical shadow of the nanowire
