However, current designs are often limited by bulky configurations, dielectric losses, and limited adaptability. Patient\u2010specific optimization\u2014essential for improving field homogeneity, boosting local SNR, and addressing anatomical variability\u2014requires redesigning each setup. To overcome these limitations, we introduce a hexagonally\u2010packed artificial dielectric, free of any lumped\u2010elements, capable of achieving a wide range of high relative permittivities (\u03b5\n                    <jats:sub>r<\/jats:sub>\n                    \u2248 30\u20131400) suitable for clinical and ultra\u2010high\u2010field MRI. We identify multilayered and in\u2010plane\u2010shifted hexagonal configurations that support compact, modular layouts. Furthermore, we combine these artificial dielectrics with passive\u2010dipole array to create a modular system for adaptable signal enhancement, tuned via electric and magnetic dipole modes by adjusting the length of conductive strips. In vivo 7T MRI results demonstrate enhanced field control and high\u2010resolution imaging. This lightweight, flexible, and modular platform enables patient\u2010specific RF field shaping, thus opening up new avenues for personalized and adaptable MRI technology.\n                  <\/jats:p>","DOI":"10.1002\/advs.77378","type":"journal-article","created":{"date-parts":[[2026,8,29]],"date-time":"2026-08-29T07:15:38Z","timestamp":1787987738000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Modular Metamaterials for Adaptable MRI Signal Control: Combining Dipole Array With a New Hexagon\u2010Based Artificial Dielectrics"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-3004-1055","authenticated-orcid":false,"given":"Santosh Kumar","family":"Maurya","sequence":"first","affiliation":[{"name":"Department of Brain Sciences Weizmann Institute of Science  Rehovot Israel"},{"name":"The Azrieli National Institute for Human Brain Imaging and Research Weizmann Institute of Science  Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7420-4055","authenticated-orcid":false,"given":"Ilan","family":"Goldberg","sequence":"additional","affiliation":[{"name":"Department of Neurology Rabin Medical Center  Petah Tikva Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1580-9964","authenticated-orcid":false,"given":"Rita","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Brain Sciences Weizmann Institute of Science  Rehovot Israel"},{"name":"The Azrieli National Institute for Human Brain Imaging and Research Weizmann Institute of Science  Rehovot Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,29]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2017.01.028"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10334\u2010022\u201001007\u20105"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.adn5195"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010017\u201001932\u20109"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202102469"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmr.2020.106877"},{"key":"e_1_2_9_8_1","doi-asserted-by":"crossref","first-page":"1726","DOI":"10.1002\/mrm.27140","article-title":"Volumetric Wireless Coil Based on Periodically Coupled Split\u2010Loop Resonators for Clinical Wrist Imaging","volume":"80","author":"Shchelokova A.
