We report on a strategy for achieving negative phase velocity (NPV) in a homogenized composite medium (HCM) conceptualized using the Bruggeman formalism. The constituent material phases of the HCM do not support NPV propagation. The HCM and its constituent phases are isotropic dielectric‐magnetic media; the real parts of their permittivities/permeabilities are negative‐valued, whereas the real parts of their permeabilities/permittivities are positive‐valued. © 2005 Wiley Periodicals, Inc.
