2D and Quasi-2D Composite and Nanocomposite Materials: Theory, Properties and Photonic Applications covers the theory, characterization and computational modeling of 2D composite materials and shows how they are used for the creation of materials for 3D structures

The book covers three major themes:

• Properties of 2D and quasi-2D composites are discussed in the context of homogenization theory. Homogenization results are discussed for spatiotemporal material composites assembled from materials which are distributed on a micro-scale in space and in time.
• New types of transport phenomena and localization in random media are addressed, with particular attention to the non-reciprocity of transport coefficients.
• Plasmonics and magneto-optics are also of particular interest. Magneto-transport and sub-wavelength resolution in electromagnetic and acoustic imaging are further considered.

This book is an important resource for materials scientists and engineers working on nanomaterials, photonic composites, and materials theory, modeling and simulations.

• Outlines major modelling techniques of 2D nanocomposites for photonic applications
• Explores how the properties of 2D nanocomposites make them suitable for use for building 3D structures
• Assesses the challenges of using 2D nanocomposites for designing new devices on a mass scale

Abstract

Here we present a short review of the theoretical description of graphene-based hyperbolic metamaterials with nonlocal quantum gain. The exact in RPA, nonlocal graphene conductivity model is used to describe the behavior of infinite and finite graphene–dielectric stacks with various input parameters, such as dielectric properties, graphene doping and photo-inversion, temperature, and excitation frequency. The exact homogenization model is presented. Transfer matrix method is used to demonstrate pulse propagation through the stack, and its amplification in case of photo-inverted graphene.
