麻省理工学院研究人员已发现一类电介质膜层 ,可在很宽角度范围里反射很宽范围的波长。J.D.Joannopoulos教授与他的同事在研究光子晶体 (即一种很像半导体 ,以其电子能带结构控制电流 ,以光子带隙控制光的结构 )期间发现了这种反射镀层。这一前景给研究人员考察电介质边界上的?
Researchers at MIT have discovered a dielectric layer that reflects a wide range of wavelengths over a wide range of angles. Professor J. D. Koannopoulos and his colleagues discovered this reflective coating during the study of photonic crystals, a structure much like a semiconductor that controls current through its electron band structure and controls light at the photonic bandgap. This prospect for researchers to examine the dielectric boundary?
