Abstract [en]

A densely arranged matrix of passive resonant two-level system is analyzed, aiming at a medium with negative macroscopic epsilon with significantly lower losses than current materials. A quality factor is used to compare the proposed material with prevalent current negative epsilon ones. Requirements are derived on two-level system parameters in terms of spatial dipole density, dipole moment and transversal relaxation times in order to obtain negative epsilon in the range of -2 to -0 and quality factors more than an order of magnitude larger than currently used materials such as silver.
