对于具有N=2超引力的极端Reissner-Nordstrom黑洞，证明了非极化电磁波和引力波的散射截面相等。非极化电磁波和引力波之间的转换截面也显示出重合。数值计算了几种电荷质量比下Reissner-Nordstrom黑洞的引力散射截面和电磁散射截面，证实了极端情况下两种散射截面的重合。
The scattering cross sections of the unpolarized electromagnetic and gravitational waves are shown to be equal for the extreme Reissner-Nordstrom black hole using N=2 supergravity. The conversion cross sections between the unpolarized electromagnetic and gravitational waves are also shown to coincide. The gravitational and electromagnetic scattering cross sections are computed numerically for Reissner-Nordstrom black holes for several charge-to-mass ratios and the coincidence between the two scattering cross sections for the extremal case is confirmed.
