Abstract

A short introduction to the theory of surface plasmon polaritons (SPPs) is given. The application of the SPPs in on-chip signal processing is discussed. In particular, two concepts of plasmonic modulators are reported, wherein the SPPs are modulated by 40 Gbit/s electrical signals. Phase and Mach-Zehnder modulators employing the Pockels effect in electro-optic organic materials are discussed. A few micro-meter long SPP absorption modulator based on a thin layer of indium-tin-oxide is reported.

Abstract

In this master thesis, the interaction of light with periodic arrays of nanometer-wide metal lines arestudied. To do so, extensive use of wave optics, waveguide and diffraction grating theories is made to better understand the interaction of light with a structure made of perfect electrical conductor (PEC) lines, both for TE and TM polarizations. In particular, we propose to gather the results of those theories in an original band structure to understand how light can couple into the array as a function of the geometrical parameters. The structure is viewed as periodic metallic waveguides simultaneously constituting a diffraction grating. The model is used to analyze quantitative numerical finite element calculations of reflectance and transmittance spectra (obtained using COMSOL Multiphysics). First, a grating of PEC lines is studied. Then an array of copper lines is analyzed and compared to the PEC lines.

Abstract

A couple of decades have passed since the advent of electromagnetic metamaterials. Although the research on artificial microwave materials dates back to the middle of the 20th century, the most prominent development in the electromagnetics of artificial media has happened in the new millennium. In the last decade, the electromagnetics of one-, two-, and three-dimensional metamaterials acquired robust characterization and design tools. Novel fabrication techniques have been developed. Many exotic effects involving metamaterials and metasurfaces, which initially belonged in a scientist’s lab, are now well understood by practicing engineers. Therefore, it is the right time for the metamaterial concepts to become a designer’s tools of choice in the landscape of electronics, microwaves, and photonics. Answering such a demand, the book “Engineering Metamaterials” focuses on the theory and applications of electromagnetic metamaterials, metasurfaces, and metamaterial transmission lines as the building blocks of present-day and future electronic, photonic, and microwave devices.

Abstract

Surface-enhanced Raman scattering (SERS) is a research technique that was discovered in the mid-1970s. SERS is a powerful and fast tool for analysis, which has a high detection sensitivity for a great number of chemical and biological molecules. However, it is in this last decade that a very significant explosion of the fabrication of highly sensitive SERS substrates has occurred using novel designs of plasmonic nanostructures and novel fabrication techniques of the latter, as well as new plasmonic materials and hybrid nanomaterials. Thus, this Special Issue is dedicated to reporting on the latest advances in novel plasmonic nanomaterials that are applied to the SERS domain. These developments are illustrated through several articles and reviews written by researchers in this field from around the world.

Abstract

Flexible Electronics platforms are increasingly used in the fields of sensors, displays, and energy conversion with the ultimate goal of facilitating their ubiquitous integration in our daily lives. Some of the key advantages associated with flexible electronic platforms are: bendability, lightweight, elastic, conformally shaped, nonbreakable, roll-to-roll manufacturable, and large-area. To realize their full potential, however, it is necessary to develop new methods for the fabrication of multifunctional flexible electronics at a reduced cost and with an increased resistance to mechanical fatigue. Accordingly, this Special Issue seeks to showcase short communications, research papers, and review articles that focus on novel methodological development for the fabrication, and integration of flexible electronics in healthcare, environmental monitoring, displays and human-machine interactivity, robotics, communication and wireless networks, and energy conversion, management, and storage.
