球对称稳态时空中标量场辐射的反射系数和透射系数

Reflection and Transmission Coefficients of Scalar Field Radiation in Steady and Spherically Symmetrical Spacetime

采用以方形势垒代替球对称稳态时空中视界附近的势垒的方法,计算了球对称稳态时空中标量场辐射的反射系数和透射系数,发现在此种类型的时空中,标量场的投射系数均接近于1,即所有的标量场都将透过势垒而传播到无穷远。

This paper calculated the reflection and transmission coefficients of scalar field radiation in steady and spherically symmetrical spacetime, with the method of substituting the potential near the event horizon with a square one, and found that the transmission coefficients in this kinds of spacetime approximates to 1. That is to say the scalar field can propagate through the horizon to reach infinity.
