J. B. Pendry it the author of a famous article, “Negative Refraction Makes a Perfect Lens” (PRL, Vol 85, No 18), about what is called left-handed materials i.e. materials having a negative refraction index. According to Sir Pendry, those left-handed materials could be used to make a perfect lens. Until now, such materials have been manufactured, but only at frequencies higher than visible. However, thanks to nanotechnologies, several research groups are making progress towards materials that would be left-handed at visible frequencies.
