Effective boundary conditions are derived for Maxwell's equations. The
se generalized impedance boundary conditions approximate the effect of
a thin dielectric layer with biperiodic conducting inclusions coverin
g a cylindrical body, on the diffraction of an electromagnetic inciden
t plane wave. The curvature appears from the first order approximation
.
