surface S only 0.1 away from the periodic structure to 0 obtain a very good agreement. In all analyses, the maximum order of the Hankel function has been limited to 15, which is sufficient for adequately representing the field scattered by a smooth perfectly conducting circular cylinder of radius a s 1.10 . In Figure 2, the scattering width revelant to the case 0 where all of the corrugations are filled with a perfectly Ž . electric conductor is also shown as reference dotted line .

Table 1 shows the maximum absolute error of the scattering width compared with the CPU time, and the dimensions of the FE linear system required to obtain the results shown in Figure 2.

It is worth noting that the previous comments can be extended to spherical periodic structures, as well as to planar periodic structures excited by a plane-wave spectrum.
