Abstract [en]

The depolarization dyadic of the cubic cavity is examined for off-center positions inside the cavity. It is shown that at an edge two of the diagonal components have ill-defined limiting values and at a corner all three diagonal components are ill defined. Figures illustrating those peculiarities are presented. The explanation is found to be the non-unique limit of the solid angle subtended by an open surface when approaching a point on its rim.
