DOI: 10.1002/elps.201800015 The cover picture shows the interrelation of the dielectrophoresis (DEP) and electrorotation (ROT) AC‐electrokinetic effects for a cell model in the membrane dispersion range. The “trick” of ROT is to translate the temporal phase shift between the induced dipole moment ( m ⃗ ) and the external field ( E ⃗ ) observed in linear inhomogeneous AC fields (top) into a spatial phase shift in circular fields (bottom). Snapshots of the induced charges illustrate the interactions with the external fields, generating DEP forces and ROT torques.
