Abstract:
Electrode configuration, comprising:a plurality of electrodes surrounding an inner space which can be filled with a suspension and being arranged to create a field cage in the inner space, each of said electrodes having a feed region and an end region, wherein each feed region is arranged for applying an electrical potential to the corresponding end region for creating field gradients in the inner space; and strip-shaped electrode segments which are connected to each end region of said electrodes, wherein said electrode segments form an arrow shape or a T-shape with rectangular extending strips with the ends of the electrode segments being directed opposite to the inner space and wherein said electrode segments are adapted to form inhomogeneous shielding fields outside the inner space that create field gradients repelling particles in the suspension away from the field cage in the inner space.
