Abstract

Abstract This paper is a preliminary report on a theoretical study of transparent shielding materials with potentially very high shielding efficiency based on quasi-periodic conductive networks. Optical transmittance as a function of beam incident angle and mesh geometry is modelled in the geometrical approximation by exact ray-tracing and compared to the analytical solution for ideal hexagonal meshes. An empirical model for rapid calculation of shielding efficiency vs frequency and mesh geometrical parameters is suggested based on numerical simulation results.
