Resumo:
The electromagnetic environment surrounding the planet Earth has a fundamental role in the preservation and development of the living creature, and perhaps the last frontier of human knowledge to be dominated completely, before we ventured to the space outside in search of new opportunity outside. This environment is only now being tamed and best known, and this endeavor has as lynch pin the use of appropriate sensors that can detect and quantify these electrical effects, to serve as a basis for the generation of theories, to explain the underlying phenomena, including in this, the sensors of atmospheric electricity. This work intends to make a comprehensive analysis of these sensor’s systems of atmospheric electricity in use today, evaluating their models of operation, its limitations and its intelligence, and producing a summarized basic specifications for development of better sensors and setting standards for metric types of the variables to be measured, to cope with the currents and future demands in this field of knowledge. Additionally, the processes involved in the calibration of these sensors will be addressed with a review of computational model based on the method of moments (MoM) and other that my be used for evaluation of electromagnetic fields emitted by remote charges patterns and electrical currents, which serve to support and basis for these calibrations.
