Optimizing Scattering Coefficients of Disordered Metamaterials Using the Finite-Difference Time-Domain Method
Keywords:
Time-Domain Method, Finite-DifferenceAbstract
A technique based on the finite-difference timedomain method is presented for calculating optical transmission and reflection of disordered nanoparticle stacks. The approach is used to optimize a nanoparticle stack exhibiting greater than 98% average absorption over the visible spectrum.
