Highly conducting wire gratings in the resonance region

We present a theoretical approach for calculating the fields diffracted by gratings made of highly conducting wires that have a rectangular shape. The fields between the wires are represented in terms of modal expansions that satisfy the approximated impedance boundary condition. Our results show th...
