  • The development and writing of this report presented considerable challenges in terms of both the study schedule and the need to avoid conveying sensitive U.S. vulnerabilities to potential adversaries. Meeting both challenges has been difficult for the study committee and staff, but every effort was made to respond to the stated need of the Technology Warning Division of the Defense Intelligence Agency (DIA) for maximum openness. I wish to express my appreciation to the members of the committee for their contributions to the preparation of this report.

  • Routing is an essential element of all but the smallest data communications networks. At one level, routing and the configuration of routers are quite simple. But as internetworks grow in size and complexity, routing issues can become at once both large and subtle. Perversely, perhaps, I am grateful for the difficult problems large-scale routing can present—as a network systems consultant, these problems are my bread and butter. Without them, the phrase "You want fries with that?" could be an unfortunate part of my daily vocabulary....

  • Most of the material in this volume is new. The first three chapters deal with three important fiber-optic components--fiber-based gratings, couplers, and interferometers--that serve as the building blocks of lightwave technology. In view of the enormous impact of rare-earth-doped fibers, amplifiers and lasers made by using such fibers are covered in Chapters 4 and 5. The last three chapters describe important applications of nonlinear fiber optics and are devoted to pulse-compression techniques, fiber-optic communication systems, and soliton-based transmission schemes....

  •  Infrared (IR) Spectroscopy: – First real IR spectra measured by Abney and Festing in 1880’s – Technique made into a routine analytical method between 1903- 1940 (especially by Coblentz at the US NBS) – IR spectroscopy through most of the 20th century is done with dispersive (grating) instruments, i.e. monochromators – Fourier Transform (FT) IR instruments become common in the 1980’s, led to a great increase in sensitivity and resolution  Raman Spectroscopy: – In 1928, C. V.

  • The questions posed in the task for this study are part of a very broad and important set of issues for the Department of Defense. To answer them required the Committee on Critical Technology Accessibility to develop its own perspective about the context within which the questions could be placed. As a result, this report provides judgments and recommendations about both the specific questions and the broader context. I wish to express my appreciation to the members of the committee for their contributions to the preparation of this report.

  • Electronic communications that are created primarily to communicate information of short-term value, such as messages reminding employees about scheduled meetings or appointments, might fall under the "TRANSITORY MESSAGES" record series. “Transitory” refers to short-term value based upon the content and purpose of the message, not the format or technology used to transmit it.

  • Not all materials can be etched in an easy and cheap way. Especially, noble metals or tantalum are stable against most of these corrosive structuring methods. Hence, precision machining may be used to generate microstructures from these metals as well as from standard metal alloys such as stainless steel or hastelloy. Depending on the material, precision machining can be performed by spark erosion (wire spark erosion and countersunk spark erosion), laser machining or mechanical precision machining.
