Abstract:
We discuss the homogenization and dimension reduction of a wave-type equation with multiple scales in space and time. To perform the homogenization together with dimension reduction, we use the method of multi-scale convergence for thin layer, which is the generalization of the two-scale convergence for a thin heterogeneous layer [M. Neuss-Radu, W. Jager (2007)]. Special attention is given to deriving the transmission condition along the interface. The study should be seen as the preliminary work to design a time-varying metasurface to control wave propagation
