This chapter is devoted to derivation of expressions for the electromagnetic fields due to known distributions of currents over arbitrary curvilinear rectangles, over bilinear surfaces, and along generalised wires and truncated cones. The first step is determination of the Lorentz potentials, from which the electric and magnetic-field vectors in the near and far zones are then evaluated.
