Engineering Physics Annotation << Back Calculation of the field of the vertical source in the layered environment I.A. Konnikov A technique for estimating the field created by a vertical source of arbitrary physical nature in a layered medium is offered, the layers being horizontally orientated. The solution to the problem is based upon employing properties of special functions. An elucidatory example is submitted. The results are valid for a broad class of problems solved by means of the Green functions technique. E-mail: konnikov_i@mail.ru
