Two Nobel Laureates present a systematic, comprehensive account of the theory, techniques, experimental data, and interpretation involved in the study of microwave spectroscopy—a subject relevant to nuclear physics, molecular structure, chemical kinetics, quantum electrodynamics, and astronomy.The material in this volume is discussed critically, systematically, and in the simplest form. The simplicity of the wording and mathematics makes most of the contents accessible to those with a very elementary knowledge of quantum mechanics and atomic physics. Although the treatment is continuously developed, each of the 18 chapters is self-contained. Nearly 200 tables and figures augment the text. Appendixes supply most of the background for research and interpretation of microwave spectra; they also contain extensive data on nuclear and molecular constants, including essentially all those determined by microwave techniques. "Equally suitable for use as a fundamental reference or advanced textbook." — U.S. Quarterly Book Review .

In 1945, Dr. Ernst Weber founded, and was the first Director of, the Microwave Research Institute (MRI) at POLYTECHNIC UNIVERSITY (at that time named the Polytechnic Institute of Brooklyn). MRI gained world-wide recognition in the 50's and 60's for its research in electromagnetic theory, antennas and radiation, network theory and microwave networks, microwave components and devices. It was also known through its series of topical symposia and the widely distributed hard bound MRI Symposium Proceedings. Rededicated as the Weber Research Institute (WRI) in 1986, the research focus today is on such areas as electromagnetic propagation and antennas, ultra broadband electromagnetics, pulse power, acoustics, gaseous electronics, plasma physics, solid state materials, quantum electronics, electromagnetic launchers, and networks. Following the MRI tradition, WRI has launched its own series of in-depth topical conferences with published proceedings. The first conference was held in October, 1990 and was entitled Directions in Electromagnetic Wave Modeling. The proceedings of the conference were published under that title by Plenum Press. This volume constitutes the Proceedings of the second WRI International Conference dealing with Ultra·Wideband Short·Pulse Electromagnetics.
