Apertures

In his moving debut collection, Matt Rasmussen faces the tragedy of his brother's suicide, refusing to focus on the expected pathos, blurring the edge between grief and humor. In "Outgoing," the speaker erases his brother's answering machine message to save his family from "the shame of dead you / answering calls." In other poems, once-ordinary objects become dreamlike. A buried light bulb blooms downward, "a flower / of smoldering filaments." A refrigerator holds an evening landscape, "a tinfoil lake," "vegetables / dying in the crisper." Destructive and redemptive, Black Aperture opens to the complicated entanglements of mourning: damage and healing, sorrow and laughter, and torment balanced with moments of relief.

Aperture Alike began when the author first walked into a rock-climbing gym, and soon after, a community, more than a decade ago. A community held up by friends, mentors, and unlikely prophets of the steep, which quickly presented a fantastic, intoxicating path; a lifestyle without equal. While the sensational, rugged, and itinerant chapters - from high peaks to depraved inner landscapes – of the outdoor life came together, one facet soon became clear. The inner journeys of those friends, mentors, and homely prophets far exceeded any outward feat of will. Aperture Alike attempts to shine light into the deeper realities, the inner character swings and the unplanned arcs of those who have both devoted themselves to an outside craft, and to defining themselves apart from it. Aperture Alike is a collection of short stories about community, about people pursuing their own immutably holy center point, in the midst of a life defined by trials and tribulation.

This book is intended as an advanced text for courses in antennas, with a focus on the mature but vital background field of aperture antennas. The book is aimed at final year, MSc, PhD and Post-Doctoral students, as well as readers who are moving from academia into industry, beginning careers as wireless engineers, system designers, in R&D, or for practising engineers. It assumes the reader has undertaken an earlier course of study on Maxwell's equations, fields and waves. Some of these topics are summarised in the early few chapters in order to provide continuity and background for the remaining chapters. The aperture antennas covered include the main types of horns, reflectors and arrays as well as microstrip patches, reflectarrays and lenses. To provide more than a superficial treatment of arrays, the topic of mutual coupling is covered in greater detail than most similar books in the area. Also included is an introduction to arrays on non-planar surfaces, which is of importance for applications that involve curved surfaces such as in aerodynamics or for making aperture antennas unobtrusive. A chapter is included on some modern aperture antennas to illustrate design techniques beyond the most common types of aperture antennas described in the early chapters. This is to show where advances have recently been made and where they could be improved in the future. Also included are selected topics of a practical nature for aperture antennas, namely fabrication and measurement.

Food has been a much-photographed subject throughout the history of photography, across genres, including art and advertising. This is the first book to survey the rich history of food in photography, and the photographers who developed new ways of describing food in pictures. Through key images, Susan Bright explores the important figures and movements of food photography to provide an essential primer, from the earliest photographers to contemporary artists.

This newly revised edition of Bryan Peterson's most popular book demystifies the complex concepts of exposure in photography, allowing readers to capture the images they want. Understanding Exposure has taught generations of photographers how to shoot the images they want by demystifying the complex concepts of exposure in photography. In this newly updated edition, veteran photographer Bryan Peterson explains the fundamentals of light, aperture, and shutter speed and how they interact with and influence one another. With an emphasis on finding the right exposure even in tricky situations, Understanding Exposure shows you how to get (or lose) sharpness and contrast in images, freeze action, and take the best meter readings, while also exploring filters, flash, and light. With all new images, as well as an expanded section on flash, tips for using colored gels, and advice on shooting star trails, this revised edition will clarify exposure for photographers of all levels.

After the end of World War II, the American road trip began appearing prominently in literature, music, movies, and photography. Many photographers embarked on trips across the U.S. in order to create work, including Robert Frank, whose seminal 1955 road trip resulted in The Americans. However, he was preceded by Edward Weston, who traveled across the country taking pictures to illustrate Walt Whitman's Leaves of Grass; Henri Cartier-Bresson, whose 1947 trip through the American South and into the West was published in the early 1950s in Harper's Bazaar; and Ed Ruscha, whose road trips between Los Angeles and Oklahoma later became Twentysix Gasoline Stations. Hundreds of photographers have continued the tradition of the photographic road trip on down to the present, from Stephen Shore to Taiyo Onorato and Nico Krebs. The Open Road considers the photographic road trip as a genre in and of itself, and presents the story of photographers for whom the American road is muse. The book features David Campany's introduction to the genre and eighteen chapters presented chronologically, each exploring one American road trip in depth through a portfolio of images and informative texts, highlighting some of the most important bodies of work made on the road from The Americans to present day.

Two alternative methods of aperture antenna analysis are described in this book.
