The coupling strength in these systems scales inversely with cavity mode volumes (V\n                    <jats:sub>m<\/jats:sub>\n                    ), yet traditional Fabry\u2013Perot cavities are diffraction\u2010limited. To overcome this limitation, we employ hyperbolic hexagonal boron nitride (hBN) to enable subdiffractional Fabry\u2013Perot\u2010like modes. In this work, we use scattering\u2010type scanning near\u2010field optical microscopy (s\u2010SNOM) to directly image polariton propagation and quantify vibrational strong coupling to weak C\u2010H bending modes in poly(methyl methacrylate) (PMMA). The isotopic composition of the hBN layer dictates the frequency range of the material's Reststrahlen band, with the strongest coupling arising when the TO phonon is closest in energy to the molecular vibrational mode. We further characterize how coupling strengths scale with the thickness of the PMMA and hBN layers, as the PMMA layer thickness dictates the number of molecules available to fill an evanescent mode volume and the thickness of the hBN dictates the size of the evanescent mode volume. Ultimately, this study demonstrates that reduced mode volumes and a more complete understanding of the coupling mechanisms to tune and control the interactions are crucial to advancement in the field.\n                  <\/jats:p>","DOI":"10.1002\/nap2.70051","type":"journal-article","created":{"date-parts":[[2026,3,24]],"date-time":"2026-03-24T08:26:08Z","timestamp":1774340768000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Tuning Vibrational Coupling Strength Between Hyperbolic Media and Organic Molecules"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-0791-5320","authenticated-orcid":false,"given":"Courtney L.","family":"Ragle","sequence":"first","affiliation":[{"name":"Interdisciplinary Materials Science Program Vanderbilt University  Nashville Tennessee USA"},{"name":"Department of Mechanical Engineering Vanderbilt University  Nashville Tennessee USA"},{"name":"Department of Chemistry Vanderbilt University  Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John E.","family":"Buchner","sequence":"additional","affiliation":[{"name":"Interdisciplinary Materials Science Program Vanderbilt University  Nashville Tennessee USA"},{"name":"Department of Mechanical Engineering Vanderbilt University  Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9302-4825","authenticated-orcid":false,"given":"In\u2010Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"Center for Quantum Technology Korea Institute of Science and Technology (KIST)  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youngji","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Vanderbilt University  Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byung\u2010Il","family":"Noh","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Auburn University  Auburn Alabama USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saurabh","family":"Dixit","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Vanderbilt University  Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Matson","sequence":"additional","affiliation":[{"name":"Interdisciplinary Materials Science Program Vanderbilt University  Nashville Tennessee USA"},{"name":"Department of Mechanical Engineering Vanderbilt University  Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahan","family":"Li","sequence":"additional","affiliation":[{"name":"Tim Taylor Department of Chemical Engineering Kansas State University  Manhattan Kansas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siyuan","family":"Dai","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Auburn University  Auburn Alabama USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
