This paper presents a new numerical procedure for the analysis of multi-row wave absorbers with selected porosities of individual elements. The theoretical model is based on the calculation of the energy flux, ie, the analysis of transmission, reflection and the energy dissipation at successive rows using the impulse response function. Empirical coefficients obtained from experiments with single screens are used in the numerical treatment of absorbers consisting of an array of screens. The analysis is backed up by an experimental program which investigates the reflection and transmission characteristics of porous walls in encountering wave groups as well as in transient wave trains representing a design wave spectrum.
