Characterization of Electromagnetic Near Fields in Industrial Systems

This paper presents a characterization of electromagnetic near fields in embedded and Internet-of-Things (IoT) systems as a tool for implementation of the fourth industrial revolution. The characterizations are carried out through the point of view of measurements and numerical modeling. The measurements were performed through an automated system and numerical modeling using specific simulation software based on finite element method. A complex electronic device was used for the measurements and numerical modeling of the electromagnetic fields, in order to simulate an IoT device that operates with wireless communication for industrial scenario. Numerical modeling was performed based on complete electronic circuit and electrical models of components. Finally, comparisons were performed between the values of the electromagnetic fields obtained through simulations and the values measured in time domain and frequency domain.
