1967年,苏联科学家Victor Veselago认为,如果有一种材料同时具有负介电常数和负磁导率,那么这种物质将能够颠覆光学世界,使光波看起来如同倒流一般,并能够在许多方面表现出有违常理的行为。1987年,美国科学家E.Yablonovitch和S.John分别从不同研究角度同时提出了具有周期介电结构的超材料——光子晶体和光子带隙的概念,掀起了光子晶体的研究热潮。 In 1967, Soviet scientist Victor Veselago believed that if one material had both negative and negative permeability, this material would be able to subvert the optical world and make the light wave look like a backflow and could show in many ways Unfair to act. In 1987, American scientists E. Yablonovitch and S. John respectively put forward the concept of photonic bandgap and photonic band gap of metamaterials with periodic dielectric structure from different perspectives of research, setting off a research craze for photonic crystals.
