Abstract

The technique presented permits calculations of the potential coefficients necessary for capacitance evaluation between conductors which are non-parallel and non-orthogonal but are inclined at an angle to one another. Reference [1] gives the equation (1) which represents the potential coefficient for any arbitrary cell shape. (Image Omitted) Si and Sj represent the areas of cells i and j, respectively, and Green's function, G, describes the interaction between the cells. For the assumptions of [1], namely, parallel or orthogonal cells, G reduces to 1/R. The case now considered is shown in Fig. 1, where two cells are inclined at an angle to one another. Using the representations shown in Fig. 1, Green's function takes on the following form.
