T-coercivity for the asymptotic analysis of scalar problems with sign-changing coefficients in thin periodic domains. <i>Electronic Journal of Differential Equations, 2021</i>(59), pp. 1-22.1072-6691https://hdl.handle.net/10877/14469We study a scalar problem in thin periodic composite media formed by two materials, a classical one and a metamaterial (also known as negative material). By applying T-coercivity methods and homogenization techniques specific to the thin periodic domains under consideration, for two geometric settings, we derive the homogenized limit problems, which both exhibit dimension-reduction effects.Text22 pages1 file (.pdf)enAttribution 4.0 InternationalSign-changing coefficientsT-coercivityThin domainsAsymptotic analysisArticle
