Abstract :
The hybrid finite element method has been extended to calculate periodic structure reflection and transmission. The method was successful in predicting the properties of a variety of planar structures, all using the same computer code. Conducting elements may extend across unit cell boundaries. The radiation boundaries may conform to the outermost part of the structure. The biconjugate gradient method was a reliable and efficient solver for these problems.
