A capacitively coupled field mapper for 2-dimensional distributed source field problems

POISSONIAN or distributed source fields occur often in present-day problems dealing with such subjects as torsional stress analysis, heat transfer, viscous fluid flow, eddy currents, and electric and magnetic fields. Since the mathematical solution of Poissonian fields has only been possible in several special cases, physical analogues have been developed for 2-dimensional fields. A highly successful physical analogue is the sandbed fluid mapper.1¿3 This paper describes an electric analogue mapper which was originated and developed by the authors. The analogue can give directly usable 2-dimensional solutions of high accuracy.
