Numerical methods for acoustic meta-material models
Jeonghun Lee, Baylor University
Host: Xu Zhang
[Abstract] [PDF]
Abstract: In this talk we consider numerical methods for some acoustic meta-material models. In the first part, we discuss a hybridized discontinuous Galerkin method for a Poisson-type problem with sign-changing coefficients, a model problem of time-harmonic meta-material equations. In the second part, we discuss mixed finite element methods for time-transient wave propagation in meta-materials.
