Higher critical current density achieved in Bi-2223 High-Tc superconductors

Journal of Radiation Research and Applied Sciences, 2016
Bi2Sr2Ca2Cu3Ox (Bi-2223) were prepared using a solid state reaction method at different sintering times and temperatures. Structural phase identifications have been done using X-Ray analysis and refinement by Reitveld method which proves the coexistence ...

An exact energy-conservation law for magneto-optical nanoparticles

JPhys Photonics
Energy conservation imposes universal limits on the scattering of light by nanoparticles (NPs). However, an exact energy conservation law for magneto-optically active NPs remains lacking.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Nonlinear Magneto-Optical Bragg Gratings

Physical Review Letters, 2006
In magneto-optical gratings the magnetic dipolar coupling superimposed on the electric dipolar one introduces nonreciprocity and spectral discrimination between circular polarization states, measured by a Zeeman-like splitting of the photonic Bragg resonances.
