A TECHNIQUE for the establishment of a field which satisfies Poisson's equation in a conducting sheet analogue is that suggested by Peierls1 and involves supplying current to the sheet so that current and voltage in the analogue represent respectively the potential and stream functions of the original field. If the current supply is to be distributed it is necessary to make an approximation by subdividing the region into a number of finite areas each fed with a current concentrated at the centre, and refinements of this method have included an examination of optimum electrode for these currents when the complete solution may be built up of a number of particular solutions2.
