description To study the electromagnetic properties of nanowires composed of various materials at infrared and optical frequencies, the dispersive nature of the material must be incorporated into the modeling approach. In the paper, the use of the complex dielectric function and mathematical models for the dispersive properties of the material, specifically in this case for Gallium Phosphide (GaP) material is discussed. Using these material models, large aspect ratio nanowires ("long nanowires") are examined. Using analytical techniques, the intensity of electric fields inside the nanowire are studied for normal incidence. Computational methods such as the finite-difference time-domain (FDTD) technique are also be used to study the behavior of finite length nanowires.
