The scattering and absorption of a double periodic array of anechoic room pyramids backed by a perfect conductor is analyzed with a surface integral equation (SIE) approach. The use of a suitable periodic Green's function as the kernel of the SIE reduces the formulation of the problem of a single pyramid. The validity, flexibility, and accuracy of the SIE approach is exemplified by comparing numerical results with measurement data for the ECCOSORB VHP family of commercially available absorbers
