Surface Polaritons

Modern Problems in Condensed Matter Sciences, Volume I: Surface Polaritons: Electromagnetic Waves at Surfaces and Interfaces describes the basic properties of surface polaritons and the methods of generating these waves in the laboratory at frequencies of interest to condensed matter physicists. The selection first elaborates on surface phonon polaritons in dielectrics and semiconductors and surface exciton polaritons from the experimental viewpoint. Discussions focus on interface polaritons; surface vibrations in anisotropic crystals; experimental methods for the excitation and study of surface polaritons; and surface vibrations in isotropic crystals. The publication then ponders on surface electromagnetic wave propagation on metal surfaces; thermally stimulated emission of surface polaritons; and effects of the transition layer and spatial dispersion in the spectra of surface polaritons. The text takes a look at surface polaritons at metal surfaces and interfaces and resonance of transition layer excitations with surface polaritons. Topics include resonance of the film phonon with the substrate surface phonon polaritons; investigations of surface modifications in ultra-high vacuum; and use of surface plasma waves for the investigation of solid-liquid and solid-solid interfaces. The selection is a dependable reference for physicists and engineers wanting to conduct research on surface polaritons.

In recent years there have been exciting developments in techniques for producing multilayered structures of different materials, often with thicknesses as small as only a few atomic layers. These artificial structures, known as superlattices, can either be grown with the layers stacked in an alternating fashion (the periodic case) or according to some other well-defined mathematical rule (the quasiperiodic case). This book describes research on the excitations (or wave-like behavior) of these materials, with emphasis on how the material properties are coupled to photons (the quanta of the light or the electromagnetic radiation) to produce “mixed waves called polaritons. · Clear and comprehensive account of polaritons in multilayered structures · Covers both periodic and quasiperiodic superlattices · Careful attention to theoretical developments and tools · Invaluable guide for researchers in this field · Shows developments from the basics to advanced topics

Covers not only near-field optical microscopy but also wider fields such as local spectroscopy, nano-scale optical processing, quantum near-field optics, and atom manipulation.

The Third Binational USA-USSR Symposium titled "Laser Optics of Con densed Matter" was held in Leningrad 1 June - 5 June 1987. This volume con tains the full text of 64 papers presented at (or prepared for) the Symposium in both plenary and poster sessions. This Symposium reestablished the very productive series of "Light Scattering" Binational Symposia which were initi ated in Moscow in 1975. Unfortunately there was an eight-year hiatus follow ing the Second Symposium in New York (1979). This interval, caused by serious chilling of the climate of USA-USSR collaboration, deprived the active scien tists on both sides of the opportunity to meet and interact in the active format of a conference. During this eight year interval there has been very rapid and intense development of scientific activity in the general area of laser optics phe nomena. The development of ultrafast laser sources has permitted rapid advances in time resolved spectroscopy and ultrafast processes; the field of optical bistability and strong nonlinearity became a hot topic; and intense work is now underway to clarify ideas of photon localization. These new dev elopments complement many advances in the study of low dimensional systems such as surfaces, new work on phase transitions, and novel studies of elemen tary excitations such as polariton-excitons in localized environments such as quantum wells and heterojunctions.

This book investigates in detail some new spoof surface plasmon polaritons (SSPPs) structures and their applications to antenna. It introduces the working principle and radiation characteristics of directional antenna, omnidirectional antenna, reconfigurable antenna and phase-mode antenna based on SSPPs structure. Especially, the irregular SSPPs structure, such as T-shaped and m-shaped SSPPs structures, is introduced to low-profile end-fire antenna with vertical polarization; the rotated SSPPs structure is applied to CP end-fire antenna and omnidirectional antenna; PIN circuit combining with SSPPs structure is used to pattern reconfigurable antenna; the novel phase-mode SSPPs antennas with multi-modes are performed too. This book proposes a continuous method to develop the potentialities of the SSPPs antenna. And the readers can study the method or ideas of the SSPPs antenna, even graft the methods to other SSPPs antenna. The book is intended for undergraduate and graduate students who are interested in SSPPs antenna technology, researchers investigating high-performance antenna, and antenna design engineers working on multi-function antenna applications.

This textbook covers the basic physics of semiconductors and their applications to practical devices, with emphasis on the basic physical principles upon which these devices operate. Extensive use of figures is made to enhance the clarity of the presentation and to establish contact with the experimental side of the topic. Graduate students and lecturers in semiconductor physics, condensed matter physics, electromagnetic theory, and quantum mechanics will find this a useful textbook and reference work.

This book describes advances in both experimental and theoretical treatments in the field of energy transfer processes that are relevant to various fields, such as spectroscopy, laser technology, phosphors, artificial solar energy conversion, and photobiology. It presents the principles and available techniques through specific examples. In addition, it examines current and possible applications, including the most recent developments, and projects future advances and research possibilities in the field.
