摘要：

After the nontrivial quantum parameters Omega(n) and quantum potentials V-n obtained in our previous research, the circumstance of a real scalar wave in the bulk is studied with the similar method of Brevik and Simonsen (Gen. Rel. Grav. 33:1839, 2001). The equation of a massless scalar field is solved numerically under the boundary conditions near the inner horizon r(e) and the outer horizon r(c) . Unlike the usual wave function Psi(omega l) in 4D, quantum number n introduces a new functions Psi(omega l n) , whose potentials are higher and wider with bigger n. Using the tangent approximation, a full boundary value problem about the Schrodinger-like equation is solved. With a convenient replacement of the 5D continuous potential by square barrier, the reflection and transmission coefficients are obtained. If extra dimension does exist and is visible at the neighborhood of black holes, the unique wave function Psi(omega l n) may say something to it.
