{ "item_title" : "Wave Propagation", "item_author" : [" James H. Williams "], "item_description" : "An engineering-oriented introduction to wave propagation by an award-winning MIT professor, with highly accessible expositions and mathematical details--many classical but others not heretofore published.A wave is a traveling disturbance or oscillation--intentional or unintentional--that usually transfers energy without a net displacement of the medium in which the energy travels. Wave propagation is any of the means by which a wave travels. This book offers an engineering-oriented introduction to wave propagation that focuses on wave propagation in one-dimensional models that are anchored by the classical wave equation. The text is written in a style that is highly accessible to undergraduates, featuring extended and repetitive expositions and displaying and explaining mathematical and physical details--many classical but others not heretofore published. The formulations are devised to provide analytical foundations for studying more advanced topics of wave propagation.After a precalculus summary of rudimentary wave propagation and an introduction of the classical wave equation, the book presents solutions for the models of systems that are dimensionally infinite, semi-infinite, and finite. Chapters typically begin with a vignette based on some aspect of wave propagation, drawing on a diverse range of topics. The book provides more than two hundred end-of-chapter problems (supplying answers to most problems requiring a numerical result or brief analytical expression). Appendixes cover equations of motion for strings, rods, and circular shafts; shear beams; and electric transmission lines.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/0/26/203/990/0262039907_b.jpg", "price_data" : { "retail_price" : "80.00", "online_price" : "80.00", "our_price" : "80.00", "club_price" : "80.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
