By implementing the Kerr metric, it is demonstrated that regions of NPV propagation are concentrated at the equator of the ergosphere, while NPV propagation is less common towards the polar regions. Increasing the angular velocity of the black hole exaggerates the NPV concentration at the equator. NPV propagation is not observed outside the stationary limit surface.", "revisions": [ { "version": "v2", "updated": "2005-08-23T14:08:21.000Z" } ], "analyses": { "keywords": [ "rotating black hole", "electromagnetic negative-phase-velocity propagation", "ergosphere", "npv propagation", "stationary limit surface" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 675497, "adsabs": "2005astro.ph..1522M" } } }
