A Practical Field Plotter Using a Hybrid Analog Computer

An automatic device for plotting the equipotential contours of two-dimensional fields, that utilizes an analog hybrid computer in conjunction with two x-y recorders has been developed. It eliminates the need for multielement probes which were used by earlier workers in this field including P. E. Green, J. K. Mickelsen, and D. H. Andrews. The main advantage of the new method is that multivalued fields in both x and y directions can be plotted using only a single element probe.
