The main feature of this book is the emphasis on "practice." This approach, unusual in the relativistic literature, may be clarified by quoting some problems discussed in the text: - the analysis of rocket acceleration to relativistic velocities - the influence of gravitational fields on the accuracy of time measurements - the operation of optical rotation sensors - the evaluation of the Doppler spectrum produced by the linear (or ro- tional) motion of an antenna or scatterer - the use of the Cerenkov effect in the design of millimeter-wave power generators - the influence of the motion of a...

The acoustic quality of a concert hall has frequently posed a mysterious puzzle, namely, what physical aspects of the sound field can produce superior sound for the listener. The author has been probing for more than adecade into the subjective qualities preferred for musical and speech sounds. The result of his extensive investigations - the discovery that four and only four independent parameters contribute effectively to good acoustics - is summarized in the present book. The capability of calculating acoustical quality at any seat in a proposed concert hall is a unique and quite useful...

Until recently, three principal classes had been known in the electrical cir- cuitry. They were as follows: 1) The lumped-constant circuit, which should be called a zero-dimensional circuit, in the sense that the circuit elements are much smaller in size as compared with the wavelength in all three spatial directions. 2) The distributed-constant circuit, which should be called a one-dimensional circuit, in the sense that the circuit elements are much smaller than the wavelength in two directions but comparable to the wavelength in one di- rection. 3) The waveguide circuit, which should be...

Over the past decade, we have witnessed a number of spectacular advances in the fabrication of crystalline semiconductor devices due mainly to the pro- gress of the different techni ques of heteroepitaxy. The di scovery of two- dimensional behavior of electrons led to the development of a new breed of ultrafast electronic and optical devices, such as modulation doped FETs, permeable base transistors, and double heterojunction transistors. Comparable progress has been made in the domain of cryoelectronics, ultrashort pulse generation, and ultrafast diagnostics. Dye lasers can generate 8 fs...

From an engineering perspective, Electrodynamics is the province of two cul tures. The most easily identified of the two is primarily concerned with phe nomena in which the propagation of electromagnetic waves is crucial. Includ ed are the designers of microwave circuits, of antennae and of many-wave length communication channels. The interests of the second group focus on dynamical processes associated with the evolution of field sources, whether these be electrons and holes migrating in a semiconductor, or currents diffus ing in a moving metal. Because the second culture is primarily...

Over the past five years, there has been an enormous increase in the inter- est in and understanding of electronic and optoelectronic devices operating in the picosecond (multigigahertz) range. This has been fueled in a sig- nificant way by the spectacular advances in picosecond laser technology, electro optic sampling, III-V devices, and wideband fiber optic systems. Partly to address these advances, a new conference jointly sponsored by the IEEE Lasers and Electrooptics Society (IEEE (LEOS)) and the Op- tical Society of America (OSA) was founded and its first meeting held in March 1985. The...

The first topical meeting on Photonic Switching was held March 18-20, 1987 in Incline Village, Nev., USA in conjunction with the second topical meeting on Optical Computing. It was sponsored by the IEEE Lasers and Electro-Optics Society and the Optical Society of America with the co operation of the IEEE Communications Society. The attendance at these meetings was well in excess of 500 persons - a measure of the growing worldwide interest in optical techniques for switching and signal process ing. Our goal in organizing the Photonic Switching meeting was to provide a forum for the...

Since the first bipolar transistor was investigated in 1947, enormous efforts have been devoted to semiconductor devices. The strong world wide competition in fabricating metal-oxide-semiconductor field-effect of develop transistor (MOSFET) memories has accelerated the pace ments in semiconductor technology. Bipolar transistors play a major role due to their high-speed performance. Delay times of about 20 ps per gate have already been achieved. Because of this rapid technologi cal progress, it is difficult to predict the future with any certainty. In 1987 a special session on ultrafast...

The ability to engineer the bandstructure and the wavefunction over length scales previously inaccessible to technology using artificially structured materials and nanolithography has led to a new class of electron semiconductor devices whose operation is controlled by quantum effects. These structures not only represent exciting tools for investigating new quantum phenomena in semiconductors, but also offer exciting opportunities for applications. This book gives the first comprehensive treatment of the physics of quantum electron devices. This interdisciplinary field, at the junction...

The field of integrated- or guided-wave optics has experienced significant and continuous growth since its inception in the late 1960s. There has been a considerable increase in research and development activity in this field worldwide and some significant advances in the realization of working in tegrated optic devices and modules have been made in recent years. In fact, there have already been some commercial manufacturing and technical ap plications of such devices and modules. The guided-wave-acoustooptics involving Bragg interactions between guided optical waves and surface acoustic...
