Abstract: In this paper, we demonstrate that for silicon nanopillars an optimum aspect ratio can be found, at which the overlapped electric and magnetic dipole resonances provide an optimized minimum forward scattering. This optimum shape depends on the aspect ratio, wavelength and refractive index of the surrounding medium. We work in the frame of numerical simulations based on Maxwell equations solved by finite element method. These results are promising for design and create novel flat optical devices.
