Calculation of electric fields by digital computer

摘要: Laplacian electric-field distributions are usually obtained with the aid of an electrolytic tank or other analogue means. Alternatively, it is possible to investigate such fields using numerical methods. The paper describes a method by which finite-difference equations set up, for multidielectric in two dimensions three at least one axis symmetry, from fundamental Laplace equation. Because these solved exact noniterative method, cover any range permittivities and boundary shapes. accuracy computer results governed difference equations, depends on fineness grid used field. Results extensive validation studies reported, comparisons made techniques.
