Modeling and Analysis of Effective Electromagnetic Parameters of Capillary System of Agricultural Soils Electric Conductivity. Low-Frequency Resonances in Empty Cylinders of Circular Section with Ideal Surface Conductivity Along Helices
ABSTRAKT
Receiving and transmitting devices of field information machines for the study of agricultural soils which determine their effective electromagnetic parameters, in particular, of the capillary system, are considered. The problem of the diffraction of a plane wave, which normally falls on an empty anisotropic cylinder with a small electric radius and ideal conductivity, which exists in them along the helices, forming a small angle with the axis of the cylinder is studied. The author has found the conditions which give rise to a powerful low-frequency resonance, which leads to a finite perturbation of the scattering diagram.
