The Poisson formula was used to explicitly construct heterogeneous continuum systems that possess comparable leading order coherent structure dynamical effects to those in discrete systems. The ensuing inverse problem was solved by means of Fourier decomposition and appropriate selection of the Fourier component. It was found that the method works very well and in full agreement with the theoretical predictions for the specific example of a φ4 field theory.
