Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.

Toward Direct Laser Writing of Dual‐Layer Metasurfaces with the Plasmonic Phase‐Change Material In3SbTe2

open access: yesAdvanced Optical Materials, EarlyView.
A simple optical programming technique is developed for fabricating plasmonic nanoantennas in a dual‐layer metasurface by crystallizing the plasmonic phase‐change material In3SbTe2 from the top and through the substrate with a subsequent reamorphization step.

Non-equilibrium dynamics of dipole-charged fields in the Proca theory

open access: yesNuclear Physics B
We discuss the dynamics of field configurations encoded in the certain class of electric (magnetic) dipole-charged states in the Proca theory of the real massive vector field.

HELMHOLTZ COILS FOR MEASURING MAGNETIC MOMENTS

open access: yesПриборы и методы измерений, 2015
The optimal configuration of the double Helmholtz coils for measuring of the magnetic dipole moments was defined. It was determined that measuring coils should have round shape and compensative coils – the square one.

The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.
