Wind-induced Vibration of Long Span Suspension Bridges in mountainous areas includes the author’s research on such bridges and adopts a combination of on-site measurements, wind tunnel tests, theoretical analyses and numerical calculations to discuss: the characteristics and parameters of the wind environment at bridge sites; the buffeting response of bridges under the effect of winds on bridges in mountainous areas; the vortex response of wide-bodied flat steel box girders; chattering characteristics (i.e. noise characteristics); and the vibration characteristics of the wind-vehicle-bridge system.Includes detailed analyses of complex wind environments at bridge sites, along with the impact of pulsating wind on such bridgesDescribes how to reduce fatigue damage caused by buffeting in bridge design and operationProposes a new wind speed calculation system and its impact on vibrationHelps bridge builders and civil and structural engineers design bridges for operation in mountainous areas

The subject of this book is the fast-developing area of research known as metamaterials/metasurfaces and some of their engineering applications. This book comprehensively presents the state of the art of metamaterials/metasurfaces from theory to applications. The theoretical side includes electrodynamics of left-handed medium, generalized Snell's law, digital coding metamaterials/metasurfaces, group theory of metamaterials, information metamaterials and metasurfaces, etc. On the application side, a wide range of design examples are discussed, including metamaterial antennas, electromagnetic interference, frequency selective surfaces, wireless power transmission and energy harvesting, cloaking and radar cross section reduction, orbital angular momentum, wireless communication, imaging, etc. The book provides researchers, engineers, and graduate students with a variety of new discoveries, results, information, and knowledge in the field of metamaterials and metasurfaces.
