摘要：
A finite element formulation combined with an asymptotic strip boundary condition is used for an analysis of the electromagnetic plane wave scattering from struts loaded with strips periodically displaced along the axial direction. The periodicity of the strips is supposed as being small when compared with the wavelength. The enforcement of this approximate boundary condition reduces the periodic vectorial problem to two coupled scalar finite element problems leading to an efficient numerical code.
