Stable vortices with topological charge of 3 and 4 are examined numerically and analytically in photonic quasicrystals created by interference of 5 as well as 8 beams, in the cases of cubic as well as...
29 March 2007,Physicists in the US have found that they can transmit terahertz light at selective wavelengths by shining it onto a metal film perforated in an aperiodic, "quasicrystal" pattern. Until ...
