Absorption of electromagnetic and gravitational waves by Kerr black holes
Article history: Received 29 August 2017 Accepted 17 September 2017 Available online 25 September 2017 Editor: M. Trodden We calculate the absorption cross section for planar waves incident upon Kerr black holes, and present a unified picture for scalar, electromagnetic and gravitational waves. We highlight the spin-helicity effect that arises from a coupling between the rotation of the black h...
متن کاملReflection, absorption and transmission of TE electromagnetic waves propagation in a nonuniform plasma slab
A numerical scheme is described to compute the reflection, absorption, and transmission coefficients of TEm,0 and plane electromagnetic waves propagating in a nonuniform plasma slab. The numerical solutions are in good agreement with theoretical solutions for two different kinds of electron density profiles. The solutions for various electron density profiles will be shown in TEm,0 mode. The me...
متن کاملEmission of Submillimeter Electromagnetic Waves by Coherent Phonons.
We report on the first observation of the emission of electromagnetic radiation from coherent lattice vibrations in a semiconductor. Coherent optical phonons are excited by ultrashort laser pulses in singlecrystal tellurium. THz frequency radiation emitted by the Dember-field-driven phonons is detected by time-resolved THz-emission spectroscopy. The measurements are complemented by optical pump...
متن کاملTotal absorption of an electromagnetic wave by an overdense plasma.
We show both theoretically and experimentally that an electromagnetic wave can be totally absorbed by an overdense plasma when a subwavelength diffraction grating is placed in front of the plasma surface. The absorption is due to dissipation of surface plasma waves (plasmons polaritons) that have been resonantly excited by the evanescent component of the diffracted electromagnetic wave. The dev...
متن کاملResonant interaction between gravitational waves, electromagnetic waves and plasma flows
In magnetized plasmas gravitational and electromagnetic waves may interact coherently and exchange energy between themselves and with plasma flows. We derive the wave interaction equations for these processes in the case of waves propagating perpendicular respectively parallel with the plasma background magnetic field. In the latter case, the electromagnetic waves are taken to be circularly pol...
