For the first step, the lamellae division, a splitting plane, basically acting like a knife, can be useful [7,140], not only for precise cutting but also for avoiding friction forces to deform the lamellae. SAR mixers were described with [7,140] and without a splitting plane [43,125, 126, 141, 142], 

SAR mixing can also be achieved by in-channel structures [7]. The splitting here is achieved by spatially separated flow guidance of split lamellae within the channel. Elevating and descending structures can serve this purpose [7]. 

SAR mixing in the truest sense is only possible for very low Reynolds numbers, typically 100 [7]. At other regimes, secondary flow superposes the SAR patterns. In terms of mixing, this may even be beneficial as a faster mixing time results. However, the typical SAR flow patterns cannot be identified by flow monitoring, so that, e.g., the design cannot be optimized by these simple means.
