I have obtained first preliminary results of my computer simulations. They were performed using FDTD Solutions of Lumerical. This program uses fine mesh of lattice points in the space and solves Maxwell's equations in ech point. By placing any object and setting light source with distnct monitors program allows to predict saome basic features and behaviors of the model.

First of my task was investigation of various features of different metals in respect to scattering cross section of the incident light. Aluminum, Silver, Gold, Copper and Palladium particles show interesting increase in the different part of the spectrum.

I have also confirmed dependency of Scattering and absorbtion cross section on surrounding refractive index. In case of 120nm silver sphere pick was shifted from 350nm to 670nm when refractive index changed from 0 to 3,5. Additional secondary pick can observed when value of n equals 2,5
