Acoustic scattering from open cavities in the time domain. <i>Electronic Journal of Differential Equations, 2019</i>(131), pp. 1-14.1072-6691https://hdl.handle.net/10877/15044This article concerns acoustic scattering from two-dimensional open cavities in the time domain. A transparent boundary condition is provided to reformulate the problem as an equivalent initial boundary value problem in the interior region of the open cavity. The well-posedness, that is, the existence, uniqueness and stability of the solution to the reduced problem, is proved via a "Laplace domain" to time domain analysis. Moreover, time domain boundary integral equations for the reduced problem are established.Text14 pages1 file (.pdf)enAttribution 4.0 InternationalTime domain acoustic scatteringOpen cavityTransparent boundary conditionWell-posednessWell-posednessBoundary integral equationArticle
