AB  - This paper presents some further results concerning active diffusers; in particular it addresses the issues of stability and the use of multiple active elements within a surface. Active diffusers have to precisely achieve a desired target impedance which is more complicated than the targets used for active absorption or control. Consequently, active diffusers are more prone to instability. Furthermore, processes developed to reduce the computational burden for active absorbers are not directly applicable to active diffusers, because it is not possible to trade off the final error achieved against the computation burden of the adaptation. These findings are demonstrated through numerical simulation and measurement.
