| Abstract: | Much experience has been gained lately in the use of a radial current source, the so-called circular electric dipole (CED), as a transmitter in transient electromagnetic (TEM) surveys. CED is a source of alternating transverse magnetic (TM) polarized field, a surface analog of a vertical electrical line in VES. In the course of two recent decades, the method has been developed theoretically and tested through the field practice. The respective published results are expected to provide an idea of TEM soundings with the optional use of either TE or TM mode. In this paper we report some new theoretical aspects and share our field experience of surveys with an CED system.© 2014, V.S. Sobolev IGM, Siberian Branch of the RAS. Published by Elsevier B.V.
