Negative Phase Velocity in Isotropic Dielectric–magnetic Mediums via Homogenization
نویسندگان
چکیده
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 whereas the real parts of their permeabilities/permittivities are positive–valued.

On 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 کاملA New Condition to Identify Isotropic Dielectric–magnetic Materials Displaying Negative Phase Velocity
Non–dissipative mediums with both simultaneously negative permittivity and permeability were first investigated by Veselago [1] in 1968. These mediums support electromagnetic wave propagation in which the phase velocity is antiparallel to the direction of energy flow, and other unusual electromagnetic effects such as the reversal of the Doppler effect and Cerenkov radiation. After the publicati...
متن کاملSimple Derivation of Dyadic Green Functions of a Simply Moving, Isotropic, Dielectric–magnetic Medium
Dyadic Green functions for time–harmonic fields in a homogeneous, isotropic, dielectric– magnetic medium, moving with constant velocity, are derived by first implementing a simple transformation and then using the dyadic Green functions available for uniaxial dielectric–magnetic mediums.
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 کاملOrthogonal–Phase–Velocity Propagation of Electromagnetic Plane Waves
In an isotropic, homogeneous, nondissipative, dielectric–magnetic medium that is simply moving with respect to an inertial reference frame, planewave solutions of the Maxwell curl postulates can be such that the phase velocity and the time–averaged Poynting vector are mutually orthogonal. Orthogonal–phase–velocity propagation thus adds to the conventional positive–phase–velocity propagation and...
