Abstract
In this chapter, we explain some important aspects of beamforming and differential arrays with a focus on the circular geometry. The problem of a DMA design is formulated while we progress in defining some useful concepts. We start with the definition of the steering vector for a plane wave with the conventional anechoic farfield model, which has an interesting structure.
