The Wave Concept in Electromagnetism and Circuits
The Wave Concept Iterative Procedure (WCIP) method has found an increasing number of users within electromagnetic theory and applications to planar circuits, antennas and diffraction problems. This book introduces in detail this new formulation of integral methods, based on the use of a wave concept with two bounded operators, and applications in a variety of domains in electromagnetics. This approach presents a number of benefits over other integral methods, including overcoming the problem of singularity, and reduced computing time. Through the presentation of mathematical equations to characterize studied structures and explanation of the curves obtained, via validated examples, the authors provide a thorough background to electromagnetism as well as a professional reference to students and researchers.

Acoustics of Fluid Media 1
Acoustics of Fluid Media 1 is intended for undergraduate students and engineering students, as well as graduate students and professionals in the industry who are increasingly faced with the need to consider acoustic constraints in the design of new products. The physical principles and theoretical foundations of acoustics in fluids are first developed, including reflection and refraction of plane and spherical waves. The book then introduces notions of signal processing applied to sound waves, followed by radiation from surface or volume acoustic sources and the use of Green’s functions, as well as the description of diffraction and scattering phenomena. The final chapters are devoted to sound propagation in ducts and room acoustics. Each chapter is accompanied by a limited number of exercises, ranging from the simple application of formulas to problems requiring a more advanced theoretical analysis or a numerical solution. Throughout the book, the theoretical results are illustrated with numerous figures obtained from measurements or numerical simulations resulting from the evaluation of complex formulas or from the use of a finite element solver.
Infrared Spectroscopy of Diatomics for Space Observation
This book describes different theoretical models developed to identify the near and mid infrared (IR) spectra of diatomic molecules isolated in the gas phase or subjected to environmental constraints, useful for the study of environmental sciences, planetology and astrophysics. The applications presented show how molecular interactions modify the near and mid IR spectra of isolated diatomics under the effect of pressure, a nano-cage (substitution site, Clathrate, Fullerene, Zeolite) or surfaces, to identify the characteristics of the perturbing environment.
Electronic Music Machines
Since 1960, with the advent of musical electronics, composers and musicians have been using ever more sophisticated machines to create sonic material that presents innovation, color and new styles: electro-acoustic, electro, house, techno, etc. music. The music of Pierre Henry, Kraftwerk, Pink Floyd, Daft Punk and many others has introduced new sounds, improbable rhythms and a unique approach to composition and notation. Electronic machines have become essential: they have built and influenced the music of the most recent decades and set the trend for future productions. This book explores the theory and practice related to the different machines which constitute the universe of musical electronics, omitting synthesizers which are treated in other works. Sequencers, drum machines, samplers, groove machines and vocoders from 1960 to today are studied in their historical, physical and theoretical context. More detailed approaches to the Elektron Octatrack sequencer-sampler and the Korg Electribe 2 groove machine are also included.
Defects in Organic Semiconductors and Devices
Defects play a key role in the physical properties of semiconductors and devices, and their identification is essential in assessing the reliability of electronic devices. Defects in Organic Semiconductors and Devices introduces the fundamental aspects of defects in organic semiconductors and devices in relation to the structure of materials and architecture of electronic components. It covers the topics of defect formation and evolution, defect measurement techniques and their adaption to organic devices, the effects of defects on the physical properties of materials and their effects on the performance and lifetime of organic devices. Identifying defects and determining their characteristics in the structure of organic devices such as OLEDs, OFETs and OPVs make it possible to better understand degradation processes and develop solutions to improve the reliability of such devices. This book is intended for researchers and students in university programs or engineering schools who are specializing in electronics, energy and materials.
Ondes Martenot with Tubes
The Ondes Martenot is one of the precursors of electronic musical instruments, and is today considered, with the desire for a return to analogue, as a cult instrument. This book, which is the result of several years of research, sheds light on the intrinsic functioning of the Ondes Martenot. Based on the study of numerous prototypes, the authors trace the historical evolution of the different techniques used: additive, multiplicative and relaxation syntheses. Often, the analysis of the functioning of these instruments demonstrates atypical technological choices, underpinned by a logic that places artistic creation at the forefront. Several models and simulations are built, so as to understand the functioning of each of the different sub-assemblies (keyboard, ribbon, intensity key, timbre filter...). At the end of the book, the complete construction of an Onde (copy of model no. 208) is described in detail. This practical realization of a facsimile is an opportunity to explore the knowhow of the electronic luthier Maurice Martenot.
Elastic Waves in Solids, Volume 2
Elastic waves are used in fields as diverse as the non-destructive evaluation of materials, medicine, seismology and telecommunications. Elastic Waves in Solids 2 analyzes the radiation, scattering and generation of these waves. It studies the emission of bulk or surface waves from sources localized on the surface of an isotropic or anisotropic solid. It then examines the scattering of a longitudinal or transverse elastic wave by one or more cylindrical or spherical heterogeneities. Finally, it explores the methods and devices used to generate and detect elastic waves, using the piezoelectric effect or the interaction with a laser beam. Accompanying figures illustrate these properties, and the text provides the orders of magnitude of some characteristic parameters. This book is intended for students completing a master’s degree in acoustics, mechanics, geophysics or engineering, as well as teachers and researchers in these disciplines.
Elastic Waves in Solids, Volume 1
Elastic waves are used in fields as diverse as the non-destructive evaluation of materials, medicine, seismology and telecommunications. Elastic Waves in Solids 1 presents the different modes of propagation of elastic waves in increasingly complex media and structures. It first studies the propagation in an unlimited solid where only the material properties are taken into account. It then analyzes reflection and transmission phenomena at an interface with a fluid or a second solid. It explains the search for propagation modes on a free surface or at the interface between two media. Finally, it proposes a study of the dispersive propagation of elastic waves guided by a plate or a cylinder. This book is intended for students completing a master’s degree in acoustics, mechanics, geophysics or engineering, as well as teachers and researchers in these disciplines.
Synthesizers and Subtractive Synthesis, Volume 2
Subtractive sound synthesis is one of the most widely used techniques in electronic music and in many analog synthesizers since the early 1960s. It is based on a simple principle, but its operation is complex, involving many parameters. It can be enhanced by a variety of effects that give the sound its authenticity, and does not simply imitate musical instruments, but can also transcribe noises present in natural soundscapes or generate entirely synthetic sounds. Synthesizers and Subtractive Sound Synthesis 2 presents practical exercises, ranging from the fundamentals to advanced functionalities. Most of the sound effects applicable to subtractive synthesis are covered: vibrato, phaser, reverb, etc. The final chapters deal with polyphony and arpeggiator-sequences.
