A team of researchers with members from Wuhan University and the University of Texas has created an artificial material that offers both negative refraction and no reflection. In their paper published in the journal Nature, ...
(PhysOrg.com) -- Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, ...
