Abstract
We numerically study the superradiant instability of charged massless scalar field in the background of charged stringy black hole with mirror-like boundary condition. We compare the numerical result with the previous analytical result and show the dependencies of this instability upon various parameters of black hole charge , scalar field charge , and mirror radius . Especially, we have observed that imaginary part of BQN frequencies grows with the scalar field charge rapidly.
