In the context of the optimization of a versatile type of metasurface consisting of inter- twined spirals printed on a dielectric substrate and loaded with discrete impedances, we propose a sim- ple development of the method of moments inter- action matrix that allows obtaining the scattered field almost instantly for any distribution of discrete loads. Simulation results for a sample design are presented to illustrate the effectiveness and validity of the method.
