Michael made a trip to to USA with a research stay at the University of Michigan, a visit of the Talpin group with seminar at the University of Chicago, and a joint workshop of the University of Minnesota and the Friedrich-Alexander University Erlangen-Nürnberg in Minneapolis.
In the summer 2016 EAM newsletter, Michael Engel as new EAM professor and the work of the research group are highlighted in an interview. The newsletter can be found here.
“We study photonic band gap formation in two-dimensional high-refractive-index disordered materials where the dielectric structure is derived from packing disks in real and reciprocal space. Numerical calculations of the photonic density of states demonstrate the presence of a band gap for all polarizations in both cases. We find that the band gap width is controlled by the increase in positional correlation inducing short-range order and hyperuniformity concurrently. Our findings suggest that the optimization of short-range order, in particular the tailoring of Bragg scattering at the isotropic Brillouin zone, are of key importance for designing disordered PBG materials.”
