Numerous designs with different coil and core arrangements have been proposed in the literature. However, the MC sizing process still involves several trial and error iterations to meet the desired specifications. This paper presents a profile methodology that uses fitting equations to extrapolate the coupling profiles and minimize the required number of finite element analysis (FEA) simulation results. A non-polarized circular coupler (FLCP) can be characterized as function of the air gap and lateral displacements using only six charging positions, whereas polarized couplers, such as the bipolar (BPP) or double-D pad (DDP), can be characterized using 18 charging positions. The methodology is validated experimentally using the FLCP, and an average error of 3% was found under different charging positions.<\/jats:p>","DOI":"10.3390\/en15176450","type":"journal-article","created":{"date-parts":[[2022,9,5]],"date-time":"2022-09-05T23:35:57Z","timestamp":1662420957000},"page":"6450","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mapping Methodology for Self and Mutual Inductance Profiles in IPT Systems"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7820-2740","authenticated-orcid":false,"given":"Emanuel G.","family":"Marques","sequence":"first","affiliation":[{"name":"DEEC, University of Coimbra, 3030-290 Coimbra, Portugal"},{"name":"DEEC, Instituto de Telecomunica\u00e7\u00f5es, 3030-290 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7529-5670","authenticated-orcid":false,"given":"Andr\u00e9 M.
