Local development of transmission and reflection of elementary field of stepwise excitation for orthotropic paramagnetic composite

Abstract

A problem of local subsurface probing of an orthotropic paramagnetic composite using a point source of stepwise external current that is parallel to a plane surface is formulated. Multidimensional Laplace–Carson transform is used to obtain transforms of the x (and y) Cartesian projection of the transmission and reflection characteristics. Analytical characteristics are determined at the origin. Expressions for the real and imaginary components of the x (and y) projections of characteristics are derived, the main properties are studied, and the computations are minimized at a predetermined accuracy using the Horner scheme. The relation of main stages and specific moments of the local development of transmission and reflection of elementary field of stepwise excitation is determined for orthotropic paramagnetic composite.
