Using of a Method of Superficial Magnetic Permeability for Reception of Dispersive Parities in Layered Structures Containing Ferrite

Questions of the electrodynamic analysis layered ferrite-s structures with magnetic waves are investigated in a great number of publications. The traditional approach to the decision of such problems consists in satisfaction of equality a magnetic field components on borders of areas. The received integrated equation then is led to system of the linear algebraic equations and dares with computer. Unknown peak factors in decomposition of fields on own functions of areas are as a result defined. At such approach for reception of well converging algorithm it is necessary to use matrixes of the big dimension that complicates the problem decision even on modern computers with high efficiency.

In offered article the method of reception of dispersive parities with use of concept of superficial magnetic permeability, as relations of normal making magnetic induction B to a tangent of making intensity H is used. Thus on borders of corresponding areas the relations components of fields are in satisfaction of equality. As a result at the strict approach to the decision of a problem of the calculation turn out less bulky that is important at the decision of practical problems.

Possibility of application of such approach to the decision of a problem of the analysis layered ferrite structures is shown. The dispersive equation for return volume waves is received.
