Abstract :
We construct a few canonical cases consisting of diffracting wedges and simple linear arrays, as steps towards predicting capacity for an entire cell, highlighting important propagation mechanisms. We show that a diffracting wedge can collapse capacity of multi-element arrays. If more that one wedge is present, the capacity increases. These effects are demonstrated theoretically and numerically through ray-tracing
