摘要：

We present a direct and very fast calculation of the low frequency tail of the spectral density of thermal noise due to the thermal motion of matter in the cylindrical mirrors generally used in gravitational wave interferometric detectors. This calculation is based on the method recently proposed by Levin, that we extend to the case of finite mirrors, allowing one to study the aspect ratio dependence of the noise. Results are found in good agreement with those found in heavier preceding approaches, and provide a useful cross-check. (C) 1998 Elsevier Science B.V.
