Book Description
This book merges theoretical and experimental works initiated in 1997 from consideration of periodical artificial dielectric structures comprising magneto-optical materials. Modern advances in magnetophotonics are discussed giving theoretical analyses and demonstrations of the consequences of light interaction with non-reciprocal media of various designs. This first collection of foundational works is devoted to light-to-artificial magnetic matter phenomena and related applications. The subject covers the physical background and the continuing research in the field of magnetophotonics.

Book Description
This comprehensive reference work satisfies the need for in-depth and multidisciplinary coverage of the current state of the art of magnetic hybrid nanoalloys (MHNAs) and their polymer and ceramic nanocomposites. MHNAs represent one of the most challenging research areas in modern science and technology. These materials are stiff and strong with remarkable electronic, mechanical, electrical, thermal and biocompatible properties, and a high potential for multifunctional applications ranging from industry to medicine. The peer-reviewed literature is already extensive, witnessing rapid progress in experimental and theoretical studies on fundamental properties as well as various advanced applications. Part 1 covers theory, modelling, and synthesis (growth and alloying mechanisms) of MHNAs. Formation mechanisms of magneto-electric multiferroic materials, magnetic carbon nanotube (CNTs), and perovskite materials, which are a novel class of next-generation multifunctional nanomaterials, are discussed. The second part focuses on characterization techniques for electrical and dielectrical, rheological, biocompatibility, and other properties, as well as applications in the industrial, agricultural, environmental, and biomedical sectors. Finally, life cycle assessment is considered as essential to the development of nanomaterials and nanoproducts from MHNAs. Advanced undergraduate and graduate students, researchers, and other professionals in the fields of materials science and engineering, polymer science, surface science, bioengineering, and chemical engineering will find comprehensive and authoritative information for solving fundamental and applied problems in the characterization and use of these multifunctional nanomaterials.

Book Description
Localized surface plasmon resonance (LSPR) in semiconductor nanostructures have attracted intense attention recently for its broad application in bio-imaging, chemical sensing, photocatalysis, and photovoltaics. Compared to the LSPR in metallic nanocrystals (NCs), LSPR in semiconductor NCs is highly tunable in the infrared region by tailoring chemical composition and stoichiometry. Moreover, LSPR along with external magnetic field allows the exploration of magneto-plasmonic coupling in single-phase semiconductors, opening up the magneto-optical ways to control charge carriers. In this thesis, we focus on the LSPR as well as magneto-optical properties of indium nitride (InN), providing valuable insights into the insufficiently researched III-V group semiconductors. Wurtzite phase InN NCs were successfully synthesized using the low-temperature colloidal method, and the plasmon intensity is tunable by changing the synthesis environment and varying doping concentrations of aluminum and titanium ions. Due to the combined effects of conduction band non-parabolicity and intraband transition, our InN NCs with different plasmon intensities have an almost fixed plasmonic energy of 0.37 eV. Besides, the optical bandgap of pure InN NCs ranges from 1.5 to 1.75 eV, depending on the reaction conditions, while that of the Al and Ti-doped InN varies from 1.65 to 1.85 eV. The plasmon-dependent phonon change is evaluated by the Raman spectroscopy. Differences in the longitudinal-optical (LO) phonon mode was observed for InN with high and low plasmon intensity. The magneto-optical properties of InN NCs were measured by the magnetic circular dichroism (MCD). The field-dependence and temperature-independence of the measured MCD spectra were investigated, and the plasmon-induced polarization of carriers was demonstrated. Tuning of the carrier polarization by varying LSPR and external magnetic field corroborates the hypothesis of non-resonant coupling between plasmons and excitons in a single-phase semiconductor. The results of this work demonstrate that LSPR can act as a degree of freedom in manipulating electrons in technologically-important III-V nanostructures and lead to potential applications in photonics and quantum computing at room temperature. Finally, InN nanowires (NWs) with LSPR were fabricated via low-temperature chemical vapor deposition (CVD) approach, laying the groundwork for the future research of LSPR and magneto-plasmonics in a one-dimensional system.

Book Description
This thesis investigates the effect of the magnetic field on propagating surface plasmon polaritons (SPPs), or surface plasmons for short. Above all, it focuses on using the magnetic field as an external agent to modify the properties of the SPPs, and therefore achieving active devices. Surface plasmons are evanescent waves that arise at metal–dielectric interfaces. They can be strongly confined (beyond the light diffraction limit), and provide a strong enhancement of the electromagnetic field at the interface. These waves have led to the development of plasmonic circuitry, which is a key candidate as an alternative to electronic circuitry and traditional optical telecommunication devices, since it is faster than the former and less bulky than the latter. Adopting both a theoretical and an experimental point of view, the book analyzes the magnetic modulation in SPPs by means of an interferometer engraved in a multilayer combining Au and Co. In this interferometer, which acts like a modulator, the SPP magnetic modulation is studied in detail, as are the parameters that have a relevant impact on it, simple ways to enhance it, its spectral dependence, and the highly promising possibility of using this system for biosensing. The thesis ultimately arrives at the conclusion that this method can provide values of modulations similar to other active methods used in plasmonics.

Book Description
Nanoplasmonics is a young topic of research, which is part of nanophotonics and nano-optics. Nanoplasmonics concerns to the investigation of electron oscillations in metallic nanostructures and nanoparticles. Surface plasmons have optical properties, which are very interesting. For instance, surface plasmons have the unique capacity to confine light at the nanoscale. Moreover, surface plasmons are very sensitive to the surrounding medium and the properties of the materials on which they propagate. In addition to the above, the surface plasmon resonances can be controlled by adjusting the size, shape, periodicity, and materials' nature. All these optical properties can enable a great number of applications, such as biosensors, optical modulators, photodetectors, and photovoltaic devices. This book is intended for a broad audience and provides an overview of some of the fundamental knowledges and applications of nanoplasmonics.

Book Description
This thesis focuses on a means of obtaining, for the first time, full electromagnetic imaging of photonic nanostructures. The author also develops a unique practical simulation framework which is used to confirm the results. The development of innovative photonic devices and metamaterials with tailor-made functionalities depends critically on our capability to characterize them and understand the underlying light-matter interactions. Thus, imaging all components of the electromagnetic light field at nanoscale resolution is of paramount importance in this area. This challenge is answered by demonstrating experimentally that a hollow-pyramid aperture probe SNOM can directly image the horizontal magnetic field of light in simple plasmonic antennas – rod, disk and ring. These results are confirmed by numerical simulations, showing that the probe can be approximated, to first order, by a magnetic point-dipole source. This approximation substantially reduces the simulation time and complexity and facilitates the otherwise controversial interpretation of near-field images. The validated technique is used to study complex plasmonic antennas and to explore new opportunities for their engineering and characterization.
