A special 3D visualization is obtained by converting electromagnetic (EM) radiation to a light field via the Wigner distribution function, which is known for discovering (revealing) hidden details. This allows for 3D diagnostics using the simple techniques of geometrical optics, which significantly facilitates the whole analysis. This simulation was applied to a complex field composed of complex beams emitted as ultra-narrow femtosecond pulses. A method was developed for the generation of phase\u2013amplitude and spectral characteristics of complex multimode radiation in a free-electron laser (FEL) operating under various parameters. The tool was successful at diagnosing an early design of the transmission line (TL) of an innovative accelerator at the Schlesinger Family Center for Compact Accelerators, Radiation Sources, and Applications.<\/jats:p>","DOI":"10.3390\/computation11080160","type":"journal-article","created":{"date-parts":[[2023,8,14]],"date-time":"2023-08-14T10:20:14Z","timestamp":1692008414000},"page":"160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Analysis and 3D Imaging of Multidimensional Complex THz Fields and 3D Diagnostics Using 3D Visualization via Light Field"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6912-1113","authenticated-orcid":false,"given":"Michael","family":"Gerasimov","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Ariel University, Ariel 40700, Israel"},{"name":"The Schlesinger Family Center for Compact Accelerators, Radiation Sources & Applications (FEL), Ariel 40700, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adnan Haj","family":"Yahya","sequence":"additional","affiliation":[{"name":"The Schlesinger Family Center for Compact Accelerators, Radiation Sources & Applications (FEL), Ariel 40700, Israel"},{"name":"Department of Physics, Ariel University, Ariel 40700, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vadim Patrick","family":"Nave","sequence":"additional","affiliation":[{"name":"Department of Physics, Ariel University, Ariel 40700, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Egor","family":"Dyunin","sequence":"additional","affiliation":[{"name":"The Schlesinger Family Center for Compact Accelerators, Radiation Sources & Applications (FEL), Ariel 40700, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Gerasimov","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Ariel University, Ariel 40700, Israel"},{"name":"The Schlesinger Family Center for Compact Accelerators, Radiation Sources & Applications (FEL), Ariel 40700, Israel"},{"name":"Department of Physics, Ariel University, Ariel 40700, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3786-6118","authenticated-orcid":false,"given":"Aharon","family":"Friedman","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Ariel University, Ariel 40700, Israel"},{"name":"The Schlesinger Family Center for Compact Accelerators, Radiation Sources & Applications (FEL), Ariel 40700, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,14]]},"reference":[{"key":"ref_1","first-page":"123","article-title":"Opportunities in THz Science","volume":"80","author":"Chamberlain","year":"2004","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"9071","DOI":"10.1038\/srep09071","article-title":"Morphology of human sweat ducts observed by optical coherence tomography and their frequency of resonance in the terahertz frequency region","volume":"5","author":"Tripathi","year":"2015","journal-title":"Sci.
