ON THE PROCESS OF INTERACTION OF DELTA-LIKE ELECTROMAGNETIC PULSE WITH HOMOGENEOUS ELECTROCONDUCTIVE HALF-SPACE
The article describes a mathematical simulation model for the process of electromagnetic field propagation and attenuation in the conductive half-space induced by a d - like electromagnetic pulse (E, B ~δ(t-z/c)) falling upon its surface. Mathematically the model is based on Maxwell equations that are the solved, considering that initial and boundary conditions are standard, by the method of Laplace transform. The work both analytically and graphically presents some space – time dependencies of electric intensity and magnetic induction in a medium with a conductivity typical of the upper layers of the earth crust (s~ 10 -5¸ 10 -4 ohm -1m -1).
