Abstract
It is known that carbon-nanotube forests, nanopillar arrays, and other high aspect-ratio conducting and semi-conducting nanostructures can have extremely low reflectance in a wide range of wavelengths, and that reflectance begins to rise at an onset wavelength. The mechanism for this behavior is poorly understood. In a previous work, we modeled conducting nanorod arrays as arrays of light sources using the Huygens-Fresnel principle and found that similar reflectance spectra could be generated. However, this simplified scalar wave model did not consider scattering effects. In this work, we improve on our previous model by calculating the scattered electromagnetic wave from a periodic conducting array. Details of our modeling and comparison with previous results will be presented.Presentation Time: Wednesday, 12-1 p.m.Zoom link: https://usu-edu.zoom.us/j/88527578213?pwd=c084OW02TXlYRHdkLzVYS25GVFhvQT09
