FIG. 2.4: Bistatic pattern of a rectangular brick
obtained by solving the C3IE on usual and refined
meshes and the CFIE on a very refined mesh.
FIG. 2.5: Bistatic pattern obtained by the RS-
C3IE.
FIG. 2.6: A view of the refined mesh around the sharp edges of the geometry.
FIG. 2.7: View of a multi-perforated wall of the combustion chamber of an aircraft engine (Courtesy of
