Abstract :
A truncated Floquet wave (TFW) formulation has been presented previously for the potential of a right-angle sectorial planar phased array of directed dipoles. In this paper, we perform an asymptotic evaluation of the spectral wavenumber integrals, uniformly valid in the vicinity of the vertex and of the shadow boundary of any FW or edge-diffracted wave species.
