Current suppression by external electromagnetic self-detecting structure in galvanomagnetic converters of electromagnetic field

Summary form only given. The paper is devoted to increasing the accuracy of measuring converters (MC) of electromagnetic fields. When designing the galvanomagnetic measuring converters of feed-through power operation on the basis of galvanomagnetic phenomenon in ferromagnetic film, it has been noticed that along with a useful signal proportional to the feed-through power there is a signal proportional to the square of the ratio frequency current flowing though the ferromagnetic film. This undesirable signal is caused by the non-uniformity of the current distribution over the film thickness. A mathematical model of converter has been built. The model of the sensor of the converter of the power flow level is presented as a multilayer dielectric waveguide with layers of finite thickness and permittivity. Between the dielectric layers, a ferromagnetic film of given geometric dimensions and conductivity has been placed.
