Networks of sign-changing metamaterials: existence and spectral properties

Kaïs Ammari, Eric Bonnetier, Alessandro Duca

We study composite assemblages of dielectrics and metamaterials with respectively positive and negative material parameters. In the continuum case, for a scalar equation, such medi…
