Abstract:
This second part of a two-paper sequence deals with the generalization
to three-dimensional (3-D) arrays of the truncated Floquet wave (TFW) diffraction
method for the full wave analysis of large arrays. This generalization potentially
includes arrays consisting of microstrip excited slots, cavity-backed apertures,and patches. The formulation is carried out first by deriving an appropriate
fringe integral equation (IE) and next by defining entire domain basis functions
in terms of global-array functions shaped as TFW diffracted rays whose analytical
expression is derived on the basis of prototype canonical problems. The efficiency
and the accuracy of this method is demonstrated by comparison with the results
of an element-by-element full wave approach for a rectangular slot array.
