Optical lenses that can see features smaller than the wavelength of light cannot be made from conventional materials. Creating “hyperlenses” that can take ultra-sharp images needs both designer materials (metamaterials) and innovative optics to be developed. Current methods for fabricating such synthetic metamaterials are complicated and involve assembling artificial cells and patterning processes. To improve the process, Texas A&M scientists developed a one-step method, which directs the self-assembly of metallic gold pillars into a special oxide using pulsed laser deposition.
