All-Angle Quasi-Self-Collimation Effect in a Rod-Type Silicon Photonic Crystal
IEEE Photonics Journal, 2015 By changing the symmetry of a photonic crystal (PC) with a rectangular lattice to straighten one of the isofrequency contours, the PC shows an all-angle quasi-self-collimation (quasi-SC) effect. To investigate the straightness of the isofrequency contour

Effect of heat treatment on structure and magnetic properties of Fe65.5Cr4Mo4Ga4P12C5B5.5 bulk amorphous alloy [PDF]
China Foundry, 2017 This study deals with the Fe65.5Cr4Mo4Ga4P12C5B5.5 ferromagnetic bulk amorphous alloy. XRD analysis showed an amorphous structure of the as-cast sample. The same method revealed that, after annealing at 973 K for τ=10 min, the sample displayed a crystalline structure with crystalline phases formed.
