METHODOLOGY FOR SCANNING DATA ANALYSIS OF NEAR ELECTROMAGNETIC FIELD
Methodology for analyzing near-electromagnetic field scanning data is proposed, which is used to process data from a near electromagnetic field scanning hardware and software complex and allows to provide graphic interpretation of the electric and magnetic components of the near electromagnetic field, which facilitates the search for local areas in which there can be potential problems in terms of providing intra-instrument electromagnetic compatibility. In the course of the work, the creation and modeling of the object of research in specialized software was performed, which represents a modified structure of a dipole antenna on a printed circuit board. Information for processing was obtained using the hardware-software complex for scanning near electromagnetic field, the spectrum analyzer and the previously developed program designed to work as part of the hardware-software control and data acquisition complex. Information on the intensity of the electromagnetic field in the near-field radiation zone of the device under test is processed according to the proposed methodology and gradient charts of distribution of the electric and magnetic components of the near electromagnetic field are comprised. The results of computer simulation of the distribution of the near electromagnetic field and data from the full-scale experiment are compared, confirming the adequacy of the proposed methodology
