This is because only a small volume for placing the coil inside the device is available, and one is only interested in the near-field characteristics of the generated magnetic field. In our study we focus on design strategies for appropriate three-dimensional induction coils by exploiting an inverse methodology. A target field is specified over a certain region and an approximation of the current density through a Fourier series expansion is derived which generates the desired field. Because of the ill-posed nature of this problem a Tikhonov regularization with a penalty term is used to calculate the unknown parameters of the Fourier series expansion. In this contribution we discuss the effect of different penalty terms, i.e. a 2-norm term, a gradient and a laplace term on the resulting current densities. Based on this, we obtain the coil windings by calculating the maximum of a current density map and applying a stream function approach."}],"conference":{"name":"Frühjahrstagung der Deutschen Physikalischen Gesellschaft","location":"Regensburg","start_date":"2019-03-31","end_date":"2019-04-05"},"_id":"1840","status":"public","date_created":"2022-04-22T10:45:39Z","publication_identifier":{"eissn":["2751-0522 "]},"main_file_link":[{"url":"https://www.dpg-verhandlungen.de/year/2019/conference/regensburg/part/ma/session/51/contribution/33"}],"title":"Designing non-conventional 3-D coils","author":[{"full_name":"Laas, Assja","first_name":"Assja","last_name":"Laas"},{"orcid_put_code_url":"https://api.orcid.org/v2.0/0000-0002-6391-6548/work/175235583","id":"35809","orcid":"0000-0002-6391-6548","last_name":"Schröder","full_name":"Schröder, Christian","first_name":"Christian"}],"project":[{"_id":"f89a05bb-bcea-11ed-9442-ed382659bc06","name":"Bielefelder Institut für Angewandte Materialforschung"}],"type":"conference","language":[{"iso":"eng"}],"date_updated":"2025-01-08T07:38:23Z"}
