Simulation of Simultaneously Negative Medium Metamaterials
… permeability of values less than 1, including negative values. If the material has negative permittivity and permeability at the same time, the material is also referred to as simultaneously negative medium (DNG medium). Such medium has several features that any natural medium is not equipped …

Investigation of resonators loaded periodic structures
… some 37 years ago, substances which exhibit simultaneously, negative permittivity ([epsilon]) and negative permeability ([mu]) over a certain range of frequencies would display some unusual phenomena such as backward waves, reversed refraction, backward Cerenkov radiation, and negative …

Anomalous photon phenomena in electromagnetic crystal systems
… in the gigahertz range that appeared to exhibit simultaneously negative values of permittivity and permeability. Such substances were known as "left-handed materials," and had been predicted to enable a variety of anomalous electromagnetic effects. Intense interests have developed in these …

Theory and application of left-handed metamaterials
Materials with simultaneously negative permittivity and permeability over a certain frequency band were first studied by Veselago in 1968, who termed such media left-handed (LH) due to the LH triad formed by the electric field vector, the magnetic field vector, and the phase propagation vector. …
