Plane Waves with Negative Phase Velocity in Isotropic Chiral Mediums
The propagation of plane waves in an isotropic chiral medium (ICM) is investigated. Simple conditions are derived — in terms of the constitutive parameters of the ICM— for the phase velocity to be directed opposite to the direction of power flow. It is demonstrated that phase velocity and power flow may be oppositely directed provided that the magnetoelectric coupling is sufficiently strong.
متن کاملPlane waves with negative phase velocity in Faraday chiral mediums.
The propagation of plane waves in a Faraday chiral medium is investigated. Conditions for the phase velocity to be directed opposite to the direction of power flow are derived for propagation in an arbitrary direction; simplified conditions which apply to propagation parallel to the distinguished axis are also established. These negative phase-velocity conditions are explored numerically using ...
متن کاملNegative Phase Velocity in Isotropic Dielectric–magnetic Mediums via Homogenization
ABSTRACT: 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 mediums; the real parts of their permittivities/permeabilities are negative–valued wherea...
متن کاملOn mediums with negative phase velocity: a brief overview
Several issues relating to oppositely directed phase velocity and power flow are reviewed. A necessary condition for the occurrence of this phenomenon in isotropic dielectric–magnetic mediums is presented. Ramifications for aberration–free lenses, homogenization approaches, and complex mediums are discussed.
متن کاملNegative– and positive–phase–velocity propagation in an isotropic chiral medium moving at constant velocity
Analysis of electromagnetic planewave propagation in a medium which is a spatiotemporally homogeneous, temporally nonlocal, isotropic, chiral medium in a co–moving frame of reference shows that the medium is both spatially and temporally nonlocal with respect to all non–co–moving inertial frames of reference. Using the Lorentz transformations of electric and magnetic fields, we show that plane ...
