Group refractive index and group velocity dispersion measurement by complex master slave interferometry [PDF]
, 2018 This paper demonstrates that the complex master slave interferometry (CMSI) method used in spectral domain interferometry (SDI) can efficiently be used for accurate refractive index and group velocity dispersion measurements of optically transparent ...

Strong group-velocity dispersion compensation with phase-engineered sheet metamaterials
, 2014 Resonant metamaterials usually exhibit substantial dispersion, which is considered a shortcoming for many applications. Here we take advantage of the ability to tailor the dispersive response of a metamaterial, introducing a new method of group-velocity ...

Identification of microstructured materials by phase and group velocities
Mathematical Modelling and Analysis, 2009 An inverse problem to determine parameters of microstructured solids by means of group and phase velocities of wave packets is studied. It is proved that in the case of normal dispersion the physical solution is unique and in the case of anomalous ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Crustal structure south of the Mexican volcanic belt, base don group velocity dispersion
Geofísica Internacional, 1996 Se estimó la estructura de velocidades de la corteza con trayectorias entre las costas de Guerrero y Michoacán, a lo largo de la zona de subducción y la ciudad de México. Esta estructura se obtuvo de la inversión de datos de dispersión de la velocidad de
