1. In combination with means having a resistive surface, a system of producing an electric field having predetermined electrical energy distribution characteristics along a first direction and predetermined electrical energy distribution characteristics along a second direction, said second direction being transversely oriented with respect to said first direction comprising,said resistive surface being provided with a first pair of opposed lateral edges and a second pair of opposed lateral edges, each of said laterally opposed edges having resistive electrode means therealong for distributively passing an electrical current into said resistive surface at incremental points of said opposed edges, respectively, and including resistance means for adjusting the distribution of current into said incremental points of said opposed edges of said resistive surface to thereby control the current supplied to said incremental points of said surface at the lateral edges thereof so as to establish a current flow between opposed lateral edges, and each said resistive electrode having a substantially uniform resistance per unit length, and said resistive surface including resistive edge extensions at a plurality of sequential points therealong, respectively, for limiting the current removed from said electrode at sequential points therealong, respectively,each said resistive electrode including a plurality of distributed conductor members along said laterally opposed edges, said distributed conductor members being carried by and in conductive contact with the surface of said resistive surface along the length of each distributed conductor member.
