dbo:abstract ديفيد ر. سميث (بالإنجليزية: David R. Smith)‏ هو فيزيائي أمريكي، ولد في 1964 في أوكيناوا في اليابان. (ar) David Richard Smith (* 1964 in Okinawa, Japan) ist ein US-amerikanischer Physiker. (de) David R. Smith is an American physicist and professor of electrical and computer engineering at Duke University in North Carolina. Smith's research focuses on electromagnetic metamaterials, or materials with a negative index of refraction. Smith obtained his B.Sc. and Ph.D. in physics from the University of California, San Diego (UCSD) in 1988 and 1994. In 2000, as a postdoctoral fellow working in the laboratory of Professor Sheldon Schultz at UCSD, Smith and his colleagues discovered the first material that exhibited a negative index of refraction. For his research in mematerials, Smith, along with four European researchers, was awarded the Descartes Prize in 2005, the European Union's top prize for collaborative research. He is known also as the first person to create a functioning cloak of invisibility that renders an object invisible in microwave wavelengths. Although the cloaking device had limited ability to conceal an object from light of a single microwave wavelength, the experiment was an initial demonstration of the potential of metamaterials, constructed composite materials with unusual optical properties, to behave in unique ways because of both their structural properties. In 2009 Reuters news service listed Smith as a potential Nobel laureate in physics. (en) David Richard Smith (Okinawa, Japão, 1964) é um físico estadunidense nascido no Japão. (pt) David R. Smith, född 1964 i Okinawa, är en amerikansk fysiker. Smith studerade vid University of California, San Diego (UCSD) där han tog bachelorexamen (B.S.) 1988 och Ph.D.-examen 1994, båda i fysik, och stannade därefter som postdoc till 1997. Efter några års verksamhet som konsult har han sedan 2001 haft en deltidstjänst som adjungerad biträdande professor i fysik vid UCSD. Han är också verksam på deltid som gästprofessor i fysik vid Imperial College London sedan 2004. Sedan 2004 har han huvudsakligen varit verksam vid Duke University, från 2007 som fullvärdig professor. 2008 bytte han till en professur i elektro- och datorteknik vid Duke. Hans forskning gäller metamaterial, bland annat sådana med negativt brytningsindex. Smith och hans kollegor vid UCSD blev år 2000 de första som kunde visa upp ett metamaterial med negativt brytningsindex, i mikrovågsområdet.
