The interaction of waves with obstacles is an everyday phenomenon in science and engineering, arising for example in acoustics, electromagnetism, seismology and hydrodynamics. The mathematical theory and technology needed to understand the phenomenon is known as multiple scattering, and this book is the first devoted to the subject. The author covers a variety of techniques, describing first the single-obstacle methods and then extending them to the multiple-obstacle case. A key ingredient in many of these extensions is an appropriate addition theorem: a coherent, thorough exposition of these theorems is given, and computational and numerical issues around them are explored. The application of these methods to different types of problems is also explained; in particular, sound waves, electromagnetic radiation, waves in solids and water waves. A comprehensive bibliography of some 1400 items rounds off the book, which will be an essential reference on the topic for applied mathematicians, physicists and engineers.
Twelve-year-old Dahlia has always lived at Silverton Manor-having spent fifty years as its resident ghost. When Oliver Day and his family show up as house-sitters the day Mrs. Tibbs, a Liberator sent by the Spectral Investigative Council, arrives to teach Dahlia the proper rules for ghosting, Dahlia can't wait to make new friends. But the unscrupulous ghost hunter, Rank Wiley, and the crooked town councilman, Jock Rutabartle, plan to rid Silverton Manor of its ghosts and sell it to the highest bidder. With her home and friendships at stake Dahlia may have to break the rules of ghosting as quickly as she learns them to solve the mystery of her death and save the manor. Equal parts charming and eerie, this ghostly caper hits all the right notes for the middle-grade audience.
