Spatially-dispersive surface modes on interfaces of layered hyperbolic metamaterials

Abstract

In this work we present the study of influence of spatial dispersion on the existence of surface modes on the interfaces with multilayered hyperbolic metamaterials (HMMs). To that end we employ operator effective medium approximation correcting the Maxwell Garnett approximation. We find out the strong effect of the layer order on the dispersion of surface waves and reveal the dispersion curves missing in the Maxwell Garnett approximation. It is also shown that due to spatial dispersion layered HMMs can sustain TE-polarized surfaces modes.
