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...

We generalize the hyper-systolic algorithm proposed in [1] for abstract data structures on massive parallel computers with np processors. For a problem of size V the communication complexity of the hyper-systolic algorithm is proportional to √ npV , to be compared with npV for the systolic case. The implementation technique is explained in detail and the example of the parallel matrix-matrix mu...

The presence of charge promotes the propensity of a rotating black hole to support the propagation of electromagnetic plane waves with negative phase velocity (NPV) in its ergosphere, whether the Kerr–Newman or the Kerr–Sen metric descriptions of spacetime are considered. Striking differences in the NPV characteristics for the Kerr–Newman and Kerr–Sen metrics emerge from numerical studies, part...

On total reflection from a half–space filled with an isotropic, homogeneous, weakly dissipative, dielectric–magnetic medium with negative phase–velocity (NPV) characteristics , it is shown here that a linearly polarized beam can experience either a negative or a positive Goos–Hänchen shift. The sign of the shift depends on the polarization state of the beam as well as on the signs of the real p...
