“…Higher order conditions have been derived in [7] and [8] for the Laplace problem and in [9,10] for the Helmholtz equation. The case of approximate transmission conditions has been studied in [11,12] for perforated thin conductors and [13] for dielectric thin periodic layers for the Laplace equation: in [11] the two first terms of the asymptotic expansion of the solution has been obtained. The case of effective transmission conditions modeling highly conductive thin sheets is treated in [14].…”

“…A review of the bibliography published during the last years shows the rise of multidimensional techniques [1][2][3][4][5][6][7][8][9] to characterize the acoustic behavior of silencers in comparison with one-dimensional techniques, due to their higher accuracy in the silencer operating frequency range.…”

“…The homogenization problem of this contribution has also been investigated in the more mathematical work [9]. In formula (29) of that work, an effective transmission condition for p is derived (which seems curious since we derive trivial transmission conditions for p in the work at hand).…”

“…In this formula, ρ denotes the density, ω the frequency, ν a normal vector on Γ 0 , pointing into the domain Ω + , and Z is a complex number, the transmission impedance, a parameter that characterizes the effective behavior of the obstacles (we cite from equation (2) of [9], where reference is given to [4]). Let us compare the empirical formula (1.2) with our findings.…”
