  Molecular Dynamics (MD) simulations of a strongly coupled binary ionic
mixture have revealed the appearance of sharp minima in the species resolved
dynamical density fluctuation spectra. This phenomenon is reminiscent of the
well-known Fano anti-resonance, occurring in various physical processes. We
give a theoretical analysis using the Quasi Localized Charge Approximation, and
demonstrate that the observed phenomenon in the equilibrium spectrum is a novel
manifestation of the Fano mechanism, that occurs at characteristic frequencies
of the system different from the conventional classical Fano frequencies.
