The se materials allow us to explore the limits of light behavior in startling ways. In the most extreme cases\, we can design materials in which light propagates with infinite phase velocity—corresponding to a refractive in dex of zero—or where light effectively stops\, becoming highly localized in space. In this lecture\, we'\;ll (interactively!) explore these un usual phenomena and consider their implications for both fundamental scien ce and future technologies LAST-MODIFIED:20260112T101859Z LOCATION:Anfiteatro PA1 (Piso -1 do Pavilhão de Matemática) do IST URL:http://df.vps.tecnico.ulisboa.pt/pt/eventos/metamaterials-for-extreme- optics-the-surprising-world-where-optical-properties-approach-zero/ X-ALT-DESC;FMTTYPE=text/html:

Nanotechnology has opened the door to metamaterials—engineered composites with optical prop erties unlike anything found in nature. These materials allow us to explor e the limits of light behavior in startling ways.

In the most ex treme cases\, we can design materials in which light propagates with infin ite phase velocity—corresponding to a refractive index of zero—or wher e light effectively stops\, becoming highly localized in space.

In this lecture\, we'\;ll (interactively!) explore these unusual pheno mena and consider their implications for both fundamental science and futu re technologies
