 et-SoSe2024.pdf).</p>  <p><strong>Abstract</strong>: What are the classic
 al bounds of the refractive index? Usually\, one would say between 1 (air)
  and 2.4 for materials such as diamond. This statement is true in the visi
 ble range. Some may say it is about 3 for semiconductors in the near-infra
 red. But have you ever wondered about the possibility of having negative v
 alues? Or just in-between\, near-zero refractive index values? This Physic
 s Colloquium aims at presenting the unique features that differentiate nea
 r-zero refractive index materials from other structured materials. We will
  focus on the study of light–matter interactions in the presence of mate
 rials/ artificial structures in which one or more of the constitutive para
 meters are near-zero. It can be either the relative permittivity or the re
 lative permeability or both. Consequently\, a decoupling of electricity an
 d magnetism is present\, the wavelength is stretched\, the phase distribut
 ion of electric and magnetic field is nearly constant\, and this is just t
 he beginning of the astonishing properties this part of photonics offers. 
 Being passionate about active and innovative teaching methodologies\, Dr M
 ichaël Lobet will use some peer instruction &amp\; generative IA pedagog
 ical techniques for presenting the above-mentioned concepts.</p>  <p><stro
 ng>Short bio</strong>: Recently appointed FNRS research associate at the 
 Physics department of the University of Namur (Namur is the capital of the
  French speaking part of Belgium\, in the South)\, Dr. Michaël Lobet is 
 also associate with Harvard (Eric Mazur's group). His work mainly focuses 
 on theoretical and numerical simulations in photonics. He is passionate ab
 out understanding light propagation inside structured materials. Therefore
 \, his research interests span over metamaterials\, photonic crystals\, li
 ght trapping management for photovoltaic systems\, plasmonics\, 2D materia
 ls\, nonlinear optics... Moreover\, Michaël is keen on science of teachi
 ng and learning and his interests are mainly active pedagogy and use of ge
 nerative IA in teaching.</p>
