Complex of numerical procedures for calculating characteristics of the pulsed electromagnetic field penetrating through slot-hole heterogeneities of the electromagnetic shield in the Earth ionospheric plasma medium
The article presents the complex of procedures for calculating characteristics of the pulsed electromagnetic field penetration through slot-hole heterogeneities of the electromagnetic shield in the Earth ionospheric plasma medium. The complex includes two calculation procedures. The first procedure is intended for evaluation of parameters of the electromagnetic field spreading through the layers of the Earth ionospheric plasma along the line from the radiation point to the shield location point. It applies a mathematical apparatus describing the electromagnetic waves spread in the medium of heterogeneous-layered plasma by means of the solution of Maxwell equation system in one-dimensional form. The second procedure consists in defining the characteristics of electromagnetic field penetrating through slot-hole heterogeneity in electromagnetic shield. The given problem concerns the type of diffraction problems solved by a method of integrated equation equivalent to Poklington equation describing the distribution of magnetic currents exited by an extraneous electromagnetic field in heterogeneity plane. The developed procedure complex allowed to analyze the characteristics of super wide-band electromagnetic pulse penetrating through electromagnetic shield slot-hole heterogeneities in the Earth ionospheric plasma medium.
