In this paper we describe some basic issues in the numerical modeling of graphene devices at optical frequencies. In the first part of the paper we analytically describe the behavior of a graphene-based directional coupler; in the second part of the paper we introduce a novel formulation of the Beam Propagation Method to show how this powerful numerical technique can also be used to describe light propagation in graphene as well as in other new emerging two-dimensional materials.

Abstract
In this paper we describe some basic issues in the numerical modeling of graphene devices at optical frequencies. In the first part of the paper we analytically describe the behavior of a graphene-based directional coupler; in the second part of the paper we introduce a novel formulation of the Beam Propagation Method to show how this powerful numerical technique can also be used to describe light propagation in graphene as well as in other new emerging two-dimensional materials.File in questo prodotto:
