A racemic approach to left-handed media.
It is established theoretically that racemic substances characterized by isomers with strong optical rotatory power are capable of producing negative refraction and focusing of arbitrarily polarized waves. A slab of such racemic material, while not chiral, acts just like Veselago's hypothetical left-handed media slab, providing subwavelength resolution as Pendry's ideal lens does and opening an avenue for optical and IR realizations. RF-microwave implementations in random and lattice fashion are also proposed.
