"This book acts as a visual vehicle to see the rock art of the Coso Range. The Coso Range sits on the edge of the Mojave Desert, just east of the Sierra Nevada. It is located within the 1.2 million acres Naval Air Weapons Station (NAWS) China Lake and contains distinctive and spectacular displays of rock art. This rock art fills the lava gorges of Renegade Canyon, Big Petroglyph Canyon, and Sheep Canyon with images of bighorn sheep, anthropomorphs, abstract geometric figures and shield-like figures. These are pecked into the dark basalt and most appear to be between 1000 to 3000 years old, although some may be older and date to the earliest occupation of the region roughly 13,000 years ago. Both the text and photography are by Paul Goldsmith, an acclaimed cinematographer. This project is highly visual in nature and provides a photographic tour of the canyons and rock art for those that will never have a chance to visit them"--Provided by publisher.

"The increasing commercial use of millimeter wavelengths for remote sensing, communications, and radar systems has driven the need for new low-cost, high performance systems, and with it, the need for quasioptical systems.Combining a general introduction to Gaussian beams and quasioptical propagation with practical applications, QUASIOPTICAL SYSTEMS provides a state-of-the-art treatment of the design of low-loss, broadband systems at microwave to submillimeter wavelegnths. the approach presented involved utilizing a beam with a Gaussian distribution of field strength perpendicular to its axis, which in turn propagates in a simple predictable fashion. Features include: A Convenient summary of Gaussian beam propagation formulas; Extensive coverage of present-day quasioptical components and their performance; In-depth coverage of dielectric material uses at millimeter and submillimeter wavelengths; An analysis of lenses and mirrors together with design techniques; and much more!This book will be of key interest to systems designers, antenna engineers, communications systems engineers, and researchers.".
