TL;DR: In this article, the propagation of various elastic waves at the surfaces of solids is considered, followed by descriptions of the many ways which have been demonstrated for transduction between surface elastic waves and electromagnetic waves.
Abstract: Many of the recently discovered characteristics and applications to electronics of surface elastic waves are discussed. First the propagation of various elastic waves at the surfaces of solids is considered, followed by descriptions of the many ways which have been demonstrated for transduction between surface elastic waves and electromagnetic waves. Surface-wave amplification, primarily in semiconductors, and wave guiding, focusing, and reflection are examined. The properties of these waves suit them for use in a number of applications, which are discussed, ranging from realization of electronic amplifiers, frequency and analog time-domain filters, and coding devices, to the modulation of light beams and the measurement of surface properties of solids. Many references to the recent surface-wave literature are included.

TL;DR: Capacitive, inductive, dielectric, piezoacoustic, chemical, biological, and microelectromechanical interdigital sensors and transducers are brought under one umbrella to discuss fabrication techniques, modeling of sensor parameters, application examples, and directions of future research.
Abstract: This review paper focuses on interdigital electrodes-a geometric structure encountered in a wide variety of sensor and transducer designs. Physical and chemical principles behind the operation of these devices vary so much across different fields of science and technology that the common features present in all devices are often overlooked. This paper attempts to bring under one umbrella capacitive, inductive, dielectric, piezoacoustic, chemical, biological, and microelectromechanical interdigital sensors and transducers. The paper also provides historical perspective, discusses fabrication techniques, modeling of sensor parameters, application examples, and directions of future research.

TL;DR: The theory and recent applications of wave propagation in periodic structures are reviewed in this paper, and speculations about future problems and development in the field of waves in periodic structure are given.
Abstract: The theory and recent applications of waves in periodic structures are reviewed. Both the Floquet and coupled waves approach are analyzed in some detail. The theoretical part of the paper includes wave propagation in unbounded and bounded active or passive periodic media, wave scatterring from periodic boundaries, source radiation (dipole, Cerenkov, transition, and Smith-Purcell) in-periodic media, and pulse transmission through a periodic slab. The applications part covers the recent development in a variety of fields: distributed feedback oscillators, filters, mode convertors, couplers, second-harmonic generators, deflectors, modulators and transducers in the fields of integrated optics and integrated surface acoustics. We also review the work on insect compound eyes, mehanical structures ocean waves, pulse compressions, temperature waves, and cholestric liquid crystals. Particles interaction with crystals is briefly reviewed, especially in the case of zeolite crystals and supelattices. Recent advances in fabrication techniques for very fine gratings me also covered. Finally, speculations about future problems and development in the field of waves in periodic structures are given.

TL;DR: In this paper, it was shown that a free surface wave is intrinsically a subsonic phenomenon and that the set of directions on a particular anisotropic elastic half-space in which such waves can travel is determined by the slowness surface of the material.
Abstract: Publisher Summary This chapter discusses that rapid progress has been made in recent years in the investigation of the basic aspects of the theory of surface waves in anisotropic elastic media. Solutions have been found to the fundamental problems concerning the existence and uniqueness of free surface waves, and in this respect, it can be claimed that a complete theory is now in existence. The outstanding new ideas have of late come from a rather unexpected quarter—namely, the theory of dislocations and results of major significance may consequently lie hidden from specialists in the dynamics of elastic materials who do not habitually attend to developments in this field. The chapter highlights that the possibility of oversight is not reduced by the dependence of the main contributions on a multitude of sources mostly located in the literature of solid-state physics, much of the precursory material having no obvious connection with elastic surface waves. Two broad insights into the character of elastic surface waves confirmed by the present study are that a free surface wave is intrinsically a subsonic phenomenon and that the set of directions on a particular anisotropic elastic half-space in which such waves can travel is determined by the slowness surface of the material.

TL;DR: This paper is a review of the theory-of laser beams and resonators and emphasis is placed on formulations and derivations which lead to basic understanding and on results which bear practical significance.
Abstract: This paper is a review of the theory-of laser beams and resonators. It is meant to be tutorial in nature and useful in scope. No attempt is made to be exhaustive in the treatment. Rather, emphasis is placed on formulations and derivations which lead to basic understanding and on results which bear practical significance.

Abstract: A large and growing number of original papers on both the experimental and the theoretical aspects of stress wave propagation is appearing in the scientific literature, and two international conferences solely concerned with the subject have been held during the last five years. The purpose of this paper is to review recent experimental and theoretical advances in the propagation of deformation waves of arbitrary shape through elastic and anelastic solids, and also to attempt to outline the problems on which present efforts are being directed and to predict probable lines of future development.
