Nonlinear eigenvalue problems for coupled Helmholtz equations modeling gradient-index graphene waveguides

22 Sep 2020 Song Jung Heon Maier Matthias Luskin Mitchell

We discuss a quartic eigenvalue problem arising in the context of an optical waveguiding problem involving atomically thick 2D materials. The waveguide configuration we consider consists of a gradient-index (spatially dependent) dielectric equipped with conducting interior interfaces... (read more)
