摘      要：In this study,we investigate the Hawking radiation in higher dimensional Reissner-Nordstrom black holes as received by an observer located at *** frequency-dependent transmission rates,which deform the thermal radiation emitted in the vicinity of the black hole horizon,are evaluated *** addition to those in four-dimensional spacetime,the calculations are extended to higher dimensional Reissner-Nordstrom metrics,and the results are observed to be sensitive to the spacetime dimension to an ***,we observe that the transmission coefficient practically vanishes when the frequency of the emitted particle approaches *** increases with frequency and eventually saturates to a certain *** four-dimensional spacetime,the above result is demonstrated to be mostly independent of the metric s parameter and the orbital quantum number of the particle,when the location of the event horizon,rh,and the product of the charges of the black hole and the particle qQ are ***,for higher-dimensional scenarios,the convergence becomes more ***,the difference between states with different orbital quantum numbers is observed to be more *** the magnitude of the product of charges qQ becomes more significant,the transmission coefficient exceeds *** other words,the resultant spectral flux is amplified,which results in an accelerated process of black hole *** relationship of the calculated outgoing transmission coefficient with existing results on the greybody factor is discussed.
