DESCRIPTION:Speaker 1: Daniele Mestriner is currently an Assistant Profe
 ssor at the University of Genoa. He has taken part in the Technical Commit
 tee of many international conferences and he works as Topic Editor for the
  journal “Applied Sciences”. His main interests include electromagneti
 c fields computation and lightning modeling. He is  author or co-author 
 of more than 50 scientific papers published in reviewed journals or presen
 ted in international conferences.   Speaker 2: Renato Procopio (M’ 03\
 , SM’17) is Associate Professor at the University of Genoa. He is co-aut
 hor of the book ‘Microgrids Design and Operation: Towards Smart Energy i
 n Cities”\, Artech House\, and of more than 150 papers published in inte
 rnational journals or presented at international conferences. He is editor
  of the international Journals Energies and Electrical and Computer Engine
 ering (power system division)\, Guest Editor of the IEEE Transaction on EM
 C Special Section “Advances in Lightning Modeling\, computation and meas
 urement”\, and of the EPSR Special Issue ““Lightning protection\, ph
 ysics and effects” and member of the IEEE Technical Committee 5 - High P
 ower Electromagnetics. He was local chair of the 19th edition of the Inte
 rnational Conference on Environment and Electrical Engineering EEEIC (Geno
 a 11-14 June 2019). He is recipient of the Emerald Literati Awards' Outst
 anding Paper accolade for the best paper published in the Electrical engin
 eering journal COMPEL (2003) for the paper “A full-Maxwell algorithm fo
 r the field-to-multiconductor line-coupling problem”.     \nThe behav
 ior of the lightning current along the channel is extremely important in t
 he evaluation of the electromagnetic fields at various distances which may
  cause disturbances or faults on electric and electronic equipment. While 
 the current at the channel-base can be measured by means of instrumented t
 owers\, the current attenuation and propagation along the channel is parti
 ally unknown. In this framework\, several models have been developed based
  on the aim of reproducing the typical characteristics of the measured ele
 ctromagnetic fields at various distances. In this lecture\, another approa
 ch is proposed: the current attenuation is evaluated starting from the ele
 ctromagnetic fields measurements. The process\, based on the Tikhonov regu
 larization technique that was derived to manage ill-posed problems\,  re
 quires some preliminary analysis involving issues such as a suitable repre
 sentation of the problem in the frequency-domain and the investigation on 
 the minimum time window in which one has to sense both the channel base cu
 rrent and the fields to get a sufficient amount of information on the atte
 nuation function.\n
