Here, some methods controlling the environment will be presented. 1) Mechanical control of the gap width: conductivity across the nanogap changes, and accordingly, the impedance changes. 2) Optical tweezing to position nanoparticles in nanogaps: conductivity changes depending on the nanoparticle\u2019s characteristics. 3) Application of phase change materials: the dielectric contrast between the gap and the sidewalls is controlled by external stimuli such as heat. Some other applications of nanogaps also will be discussed.<\/span><\/p>\n<\/div>\n<p class=\"x_MsoNormal\"><span style=\"text-decoration: underline;\"><b><span lang=\"EN-US\">Biography<\/span><\/b><\/span><b><span lang=\"EN-US\"><span style=\"text-decoration: underline;\">:<\/span><br \/>\n<\/span><\/b><\/p>\n<p class=\"x_MsoNormal\"><span lang=\"EN-US\" data-olk-copy-source=\"MessageBody\">Dukhyung Lee got his Ph.D. in physics from Seoul National University (SNU) in 2018, focusing on nanophotonics, particularly plasmonics in metal nanostructures. After graduation, he broadened his research scope at several institutions, including SNU, KIST, UNIST, and NIMS, enhancing his expertise in optical spectroscopy and simulations. He joined UM6P in September 2024. Currently, his research interests include active metamaterials and strong light-matter interactions.<\/span><\/p>\n<p class=\"x_MsoNormal\"><span style=\"text-decoration: underline;\"><b><span lang=\"EN-US\">Localization<\/span><\/b><\/span><span lang=\"EN-US\"><span style=\"text-decoration: underline;\">:<\/span> Ryad 8, 1st Floor.<\/span><\/p>\n<p class=\"x_xmsonormal\"><span style=\"text-decoration: underline;\"><b><span lang=\"EN-US\">Teams Link<\/span><\/b><\/span><span lang=\"EN-US\"><span style=\"text-decoration: underline;\">:<\/span><br \/>\n<span style=\"color: #3366ff;\"><a style=\"color: #3366ff;\" href=\"https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_NjkxYTFkOTEtMTA2NC00YjE2LWJkYzktMmI2NWE0ZDRmOTRh%40thread.v2\/0?context=%7b%22Tid%22%3a%2239626157-a047-4689-87a2-6fa645cb5cb7%22%2c%22Oid%22%3a%22d3bbb26e-fd14-45df-84fa-adbf01366dcc%22%7d\">https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_NjkxYTFkOTEtMTA2NC00YjE2LWJkYzktMmI2NWE0ZDRmOTRh%40thread.v2\/0?context=%7b%22Tid%22%3a%2239626157-a047-4689-87a2-6fa645cb5cb7%22%2c%22Oid%22%3a%22d3bbb26e-fd14-45df-84fa-adbf01366dcc%22%7d<\/a><\/span><br \/>\n<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Control of electromagnetic waves in nanogaps Lee Dukhyung University Mohammed VI Polytechnic (Institute of Applied Physics) IAP Physics Seminar Series will occur on Tuesday 17 December, at 11:15 at the UM6P campus (Ryad 8, 1st floor).
