In this work a spatial light modulator (SLM) and a ring slit are used to generate superpositions of higher-order Bessel beams. We show that even though these fields do not carry any orbital angular momentum (OAM) a rotation in their intensity profile is evident, agreeing well with the theoretical prediction.
