Examples in use for many decades already are the directional arrays used in
AM broadcasting, where all elements (towers) in the array are driven. The
element spacings & orientations, and the relative power & phase applied to
each element determine the net radiation pattern of the array.

Let me ask another question. Since a gaussian array is in equilibrium
it can be placed in a complex circuit to generate a pass filter or
something like that. Does this fact provide any advantages? Also with
regard to the irregular radiation field the Gaussian array with a
single feed point can duplicate the present broadcasting method of
arrays where phasing harneses would be required. Just a thought
