Abstract
The results of FDTD modeling of the spectral reflection characteristics of periodic systems with unit cells in the form of cylinders and cones corresponding to the morphology of the porous and black silicon layer presented. The antireflection behavior of these systems with a characteristic size on the order of several hundreds of nanometers is analyzed. The properties of reflection depending on the geometric parameters of unit cells and the angle of incidence of light rays are investigated. It is shown that periodic systems with cones are superior in antireflection properties to systems with cylinders.
