Abstract

This paper describes an innovative test procedure for the characterization of a new field sensor prototype sensitive to amplitude-modulated signals and designed to be installed as a detector unit in an intelligent network for the localization of global system for mobile communications (GSM) cellular phones aboard an aircraft. The response of the sensor, expressed by the activation probability in a given operative condition, is obtained as a function of frequency, voltage supply, and incident field level. Index Terms--Aircraft electromagnetic (EM) environment, cellular phone, portable electronic device (PED), reverberation chamber (RC).

Abstract

The paper reports the results of the test and modelling activities carried out on large commercial supercapacitor cells at high current. Four commercials cells, with rated capacitance of 3000 F and rated voltage of 2.7 V, are considered. All cells are submitted to consecutive charge/discharge cycles at constant current. A test current in the range 80-130 A is used, which is comparable with the maximum operating current (up to 150 A) that the cells can reach in practical operations. A circuit model of the cells, able to reproduce the most relevant dynamic behavior, with a good compromise between accuracy, simplicity and robustness of the model's parameters, is also developed and validated against the experimental data. It is shown that all the investigated commercial cells are characterized by similar phenomena and comply with the same circuit model. Moreover, it is shown that the circuit parameters of the cells are in the same range and are weakly dependent on the test current. The obtained circuit parameters are accurately reported for all the cells and made fully accessible to users.
