✦ Synopsis

we mtroduce a fourth-order energy for the three-chmenslonal wave equation m rectangular domams with second-order absorbmg boundary condltlons A decay rate of the energy m the domam with respect to time IS estimated m terms of the boundary integral Absorbmg boundary conchtlons considered m tins paper mclude the treatment of the case of anmlnlatlon of obliquely incident waves arrlvmg at the boundary Numerical results are also shown
