The development of devices for focusing radiation on desired targets is of great importance in different fields of science and communication technologies as it would allow the creation of more efficient optical instruments. In this study, we explored the dispersion of dielectric spherical nanoparticles using elements from Mie’s theory. There was evidence that the form of dispersed radiation patterns depends on factors such as the size of particles and the wavelength of incident radiation. The knowledge regarding radiation dispersion could be applied in the development of nanoantennas, as well as new nanotechnology devices and arrangements.
