Sažetak
In this work, homogenization of Maxwell's equations inside periodic heterogeneous microstructure in frequency domain is considered. In electrical engineering, especially in radioengineering, modelling and analysis of electromagnetic problems is usually made in frequency domain. Engineers are more interested in signal spectrum, or how some portions of spectrum behaves in their system than in time domain simulations. Reason for that lies in material behavior which is usually a function of frequency. Using peri odic structures as building blocks of lenses, metasurfaces, filters and other objects is very popular in the last 20 years. In order to model and produce artificiall objects it is necessary to understand homogenization limit of Maxwell's equations and behaviour of effective parameters according to frequency of incoming wave. In this paper we will focus on electromagnetic scattering problem on heterogeneous object, lens, made of periodic inclusions. Using Two-Scale Convergence we will obtain unit cell problems that we treat numerically. All simulations shown in this talk are made in FEniCS.
