"Besides introductory remarks on gravitational, magnetic, electrostatic, direct current electrical and electromagnetic fields, this book contains detailed solutions of Laplace and electromagnetic wave equations by the method of separation of variables. Behaviors of the scalar and vector potential and nature of the solutions of these boundary value problems are shown, as also the use of complex variables and conformal transformation, Green's theorem, Green's formula and Green's functions. Finite elements and finite difference methods for two-dimensional potential problems are discussed in considerable detail. The analytical continuation of the potential field and inverse theory, used for interpretation of potential field data, is demonstrated."--Jacket.
