{"product_id":"an-analytic-theory-of-multi-stream-alexander-figotin-9789811209192","title":"An Analytic Theory of Multi-Stream Electron Beams in Traveling Wave Tubes","description":"The Traveling Wave Tubes (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals as well as numerous applications such as radar, television and telephone satellite communications. This monograph is devoted to the author's original theoretical developments in the theory of a traveling wave tube (TWT).Most of the monograph is the author's original work on an analytical theory of TWTs. It is a constructive Lagrangian field theory of TWT in which the electron beam (e-beam) is represented by one-dimensional multi-stream electron flow and the guiding slow-wave structure is represented by possibly non-uniform multi-transmission line (MTL). The proposed analytic theory accounts for a number of electron plasma phenomena including space-charge effects such as electron-to-electron repulsion (debunching), convective instabilities, wave-particle interaction, amplifying waves and more. It allows, in particular, to (i) identify origins of the wave-particle interaction and the system convective instability (exponential growth); (ii) evaluate the energy transfer rate from the e-beam to the electromagnetic radiation; (iii) identify instability modal branches which under condition of sufficiently strong coupling between the e-beam and the MTL can cover ideally all frequencies.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Alexander Figotin\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9811209197\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789811209192\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e World Scientific Publishing Company\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 11\/13\/2020\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 500\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 2.18lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.61h x 6.69w x 1.06d","brand":"Alexander Figotin","offers":[{"title":"Hardcover","offer_id":43941462769919,"sku":"9789811209192","price":158.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_53c95876-c967-42c7-a4ae-b442c91ecff8.jpg?v=1681453061","url":"https:\/\/www.whiterainbookhouse.com\/products\/an-analytic-theory-of-multi-stream-alexander-figotin-9789811209192","provider":"WR Book House","version":"1.0","type":"link"}
