The volume-surface integral equation (VSIE) is modified to solve the scattering problem of a wedge absorber not only for side incidence but also for forward incidence. The model is assumed to consist of infinitely periodic lossy wedges backed by a perfect conductor. By taking advantage of periodicity in the x-direction and homogeneity in the z-direction of the wedge absorber geometry, the infinite limits on volume and surface integrals are reduced to surface and line integrals, respectively, over only one period. To solve the modified VSIE numerically, a point matching technique is applied. The computer code was checked by calculating the reflection coefficient of a lossy slab backed by a perfect conductor.
