The present invention relates to a stabilizer combination for stabilizing IR absorbers, comprising a) at least one stabilizer based on phosphine, b) at least one stabilizer based on phosphite, and c) at least one phenolic antioxidant stabilizer. Such methodology may also be implemented as a system using logic for performing the various operations. A first hybridization condition is established in the test system. The beamforming information is usable for controlling, at the first transceiver, the transmitting of the plurality of beams.
