| Abstract(in English) | We study the asymptotic analysis of the bottom reflected acoustic field radiated from the sound source. A uniform asymptotic solution applicable in wide ranges is derived by asymptotically evaluating the integral representation of the acoustic field after decomposing the reflection coefficient into two terms; one of them has a branch point and the other no branch point. We compare the uniform asymptotic solution with the reference solution calculated numerically and confirm its validity and utility. We clarify numerically the applicable ranges of the conventional field representations. |
