| Abstract: | The theoretical formulas of electromagnetic field excited by any directed source in cylindrical multilayer media are given in this paper. It can be easily computed by using the successive derived method. The relational curves between the magnetic field strength in receiver and the invasion radius are given also on axial and radius directed source of electric-dipole or magnetic-dipole separately. |
