Study on the optical properties of nanowires using FDTD method

Finite-difference time-domain studies of a variety of cylinder arrays with nanometer-scale diameters (nanowires) interacting with light are presented. Scattering and absorption cross sections for metallic nanoscale objects can be obtained from such calculation. The method is verified by comparing the analytical results for cylindrical nanowires. Calculate the optical properties of Ag nanowires and study the explicit time-domain behavior of more cylinders.
