Abstract :
In order to understand and quantify the high-frequency wave processes associated with Floquet wave (FW) edge diffraction, this paper deals with the canonical Green´s function of a semiinfinite phased array of dipoles in free space. The diffracted field contributions due to each incident FW field are cast in a dyadic form that highlights the behavior of TE and TM waves. Special attention is given to evanescent diffracted fields, which are associated with high order FWs.
