[null,null,null,"Sommario/riassunto","Since the mid-1990s, Bangladesh's banking sector has grown considerably. Despite the boom and the government's efforts to increase access in rural areas, rural financial markets have shrunk in relative terms. As a result, access to finance by micro, small, and medium-size enterprises and marginal, small, and medium-size farmers - the \"\"missing middle\"\" - remains limited, which is significant because these groups are the engines of growth in rural Bangladesh in terms of employment, contribution to GDP, and prospects for future "]

The authors describe the precursors and history of metasurfaces before moving on to explore the physical insights that can be gained from the material parameters of the metasurface. They also present how to compute the fields scattered by a metasurface, with known material parameters, being illuminated by an arbitrary incident field, as well as how to realize a practical metasurface and relate it its material parameters to physical structures.The book finishes with a discussion of the future of the field\"--"]
