Extreme ultraviolet (EUV) light enables attosecond physics and nanoscale semiconductor lithography. Unfortunately, all materials absorb it due to its large photon energy, and no transmissive optics exist. Prof. Ossiander introduces how this lack of optical elements can be overcome by using ultrathin metasurfaces comprising millions of high-refractive-index holes. Then, he will examine if these new short-focal-length optics for the EUV provide a route to light microscopy combining attosecond time and sub-micron-level spatial resolution.
