Abstract [en]

A three-dimensionally isotropic negative permeability of a neutral alkali-metal atomic medium, in which a fine-structure magnetic dipole-allowed transition in terahertz band is pumped for population transfer (and hence incoherent gain for negative permeability can be realized), is suggested based on quantum optical approach. The effects relevant to photonic resonance and quantum coherence are involved in the present quantum optical scheme of pumped magnetic-dipole allowed transition. The incoherent-gain assisted atomic medium (with fine-structure transition involved) may have some attractive features, e. g., three-dimensionally isotropic and homogeneous negative permeability for high-gain wave amplification at terahertz frequencies. Such a gain-assisted negative-permeability medium can be a candidate of magnetically resonant materials for artificial composite metamaterials, e.g., it may serve as a substrate of lossy negative-index materials for loss compensation or as a supporting medium for high-gain amplification of a TE-mode surface plasmon-like wave.
