Geometric phase and o-mode blueshift in a chiral anisotropic medium inside a Fabry-P´erot cavity
Anomalous spectral shift of transmission peaks is observed in a Fabry-P´erot cavity filled with a chiral anisotropic medium. The effective refractive index value resides out of the interval between the ordinary and ...
Transmission and Reflection Spectra of a Raman Induced Grating in Atomic Media
The spectral properties of an electromagnetically induced grating that is based on the spatial modulation of the Raman gain in the field of a standing pump wave in a three-level homogeneous medium have been discussed. It ...
Effects of processing parameters on the morphology, structure, and magnetic properties of Cu1−xFexCr2Se4 nanoparticles synthesized with chemical methods
Cu1−xFexCr2Se4 nanoparticles with x = 0, 0.2, and 0.4 were synthesized via thermal decomposition of metal nitrate or chloride salts and selenium powder using different precursor compositions and processing details. Single ...
