Book Description
The Terahertz Band (0.1-10 THz) is envisioned as a key a wireless technology that will enable Terabit-per-second data rate, which is expected to become a reality within the next five years. One of the main problems of this technology is the lack of compact high-power signal sources in order to overcome the very high path loss. Novel plasmonic devices based on nanomaterials such as graphene are a new promising alternative capable to efficiently operate at THz frequencies. In this thesis, the performance of a graphene-based plasmonic device for on-chip direct generation, modulation, and detection of THz signals is proposed, modeled and simulated using a finite-difference-based multi-physics simulation platform, which can handle both hydrodynamic model equations and Maxwell's equations. The device is based on a gated High Electron Mobility Transistor (HEMT) with graphene as the 2DEG channel, where a THz plasmonic signal is generated by implementing an asymmetric boundary condition at the source and drain. Moreover, this setup offers the possibility to modulate the generated signal by changing the applied current density.

Book Description
Graphene demonstrates interesting electrical, optical, and optoelectronic properties. A number of other one-atom-thick material structures have been discovered and studied. Industrially applicable technologies for these structures are currently under active development. In spite of enormous research in the area of devices based on graphene, the number of extensive review publications on THz devices based on graphene is small. This review volume would fill the gap. Researchers and engineers working in the fields of electronics and plasmonics can use it to understand the influence of plasmonics on device performance. The book can be also be used as a required text for doctorate courses and as a supplementary material for postgraduate courses. The material presented in the book is reviewed in detail in Chapter 1. Chapter 2 discusses the electronic and plasmonic properties of graphene and heterostructures based on graphene for all devices. Chapters 3–7 focus on the concepts of detectors and emitters with a special emphasis on plasmonic enhancement of those devices as well as on population inversion and lasing.

Book Description
Multi-point Cooperative Communication Systems: Theory and Applications mainly discusses multi-point cooperative communication technologies which are used to overcome the long-standing problem of limited transmission rate caused by the inter-point interference. Instead of combating the interference, recent progress in both academia and industrial standardizations has evolved to adopt the philosophy of “exploiting” the interference to improve the transmission rate by cooperating among multiple points. This book addresses the multi-point cooperative communication system systematically giving the readers a clear picture of the technology map and where the discussed schemes may fit. This book includes not only the theories of the paradigm-shifting multi-point cooperative communication, but also the designs of sub-optimal cooperative communication schemes for practical systems. Ming Ding is a senior researcher at Sharp Laboratories of China; Hanwen Luo is a professor at Shanghai Jiao Tong University.

Book Description
This book is meant as an introduction to graphene plasmonics and aims at the advanced undergraduate and graduate students entering the field of plasmonics in graphene. In it different theoretical methods are introduced, starting with an elementary description of graphene plasmonics and evolving towards more advanced topics. This book is essentially self-contained and brings together a number of different topics about the field that are scattered in the vast literature. The text is composed of eleven chapters and of a set of detailed appendices. It can be read in two different ways: Reading only the chapters to get acquainted with the field of plasmonics in graphene or reading the chapters and studying the appendices to get a working knowledge of the topic. The study of the material in this book will bring the students to the forefront of the research in this field.

Book Description
Hyperbolic metamaterials were originally introduced to overcome the diffraction limit of optical imaging. Soon thereafter it was realized that hyperbolic metamaterials demonstrate a number of novel phenomena resulting from the broadband singular behavior of their density of photonic states. These novel phenomena and applications include super resolution imaging, new stealth technologies, enhanced quantum-electrodynamic effects, thermal hyperconductivity, superconductivity, and interesting gravitation theory analogs. Here I review typical material systems, which exhibit hyperbolic behavior and outline important new applications of hyperbolic metamaterials, such as imaging experiments with plasmonic hyperbolic metamaterials and novel VCSEL geometries, in which the Bragg mirrors may be engineered in such a way that they exhibit hyperbolic properties in the long wavelength infrared range, so that they may be used to efficiently remove excess heat from the laser cavity. I will also discuss potential applications of self-assembled photonic hypercrystals. This system bypasses 3D nanofabrication issues, which typically limit hyperbolic metamaterial applications. Photonic hypercrystals combine the most interesting features of hyperbolic metamaterials and photonic crystals.
