Impact of the inherent periodic structure on the effective medium description of left-handed and related meta-materials

Th. Koschny, P. Markos, E. N. Economou +3

We study the frequency dependence of the effective electromagnetic parameters of left-handed and related meta-materials of the split ring resonator and wire type. We show that the…

Stability of Fe-based alloys with structure type C6Cr23

M. Widom, M. Mihalkovic

Bulk metallic glass forms when liquid metal alloys solidify without crystalization. In the search for Iron-based bulk glass-forming alloys of the metal-metalloid type (Fe-B- and Fe…

Quasicrystal approximants with novel compositions and structures

M. Mihalkovic, M. Widom

We identify several new quasicrystal approximants in alloy systems in which quasicrystals have not been previously reported. Some occur in alloys with large size contrast between t…

Order-disorder transition in the Cd-Ca cubic approximant

M. Widom, M. Mihalkovic

Recent experiments discovered an order-disorder transition occuring at low temperatures in large unit 1/1 cell cubic approximants of the stable Cd-based binary alloy quasicrystals.…

Equilibrium structure of decagonal AlNiCo

S. Naidu, M. Mihalkovic, M. Widom

We investigate the high temperature decagonal quasicrystalline phase of AlNiCo using a quasilattice gas Monte-Carlo simulation. To avoid biasing towards a specifi…
