Abstract : In this document, we analyze via the theory of matched asymptotics the propagation of a time domain acoustic wave in a junction of thin slots. This allows us to propose Improved Kirchhoff conditions for the 1D limit problem. These conditions are analyzed and validated numerically.

Keywords : Matched asymptotics Wave equation Time domain Thin slots Kirchhoff conditions
