Photonic doping of epsilon-near-zero media

Abstract

Doped photonics Doping semiconductor materials with impurity atoms enables control of the optoelectronic properties that enhance functionality. Liberal et al. describe numerically and experimentally an analogous doping effect for a group of photonic materials. They introduced a dielectric into an otherwise nonmagnetic material, which produced a magnetic response. The generality of the method should allow the design of photonic materials with enhanced and controlled electromagnetic response. Science , this issue p. 1058
