Local Dielectric Spectroscopy of Nanocomposite Materials Interfaces

open access: yes, 2009
Local dielectric spectroscopy is performed to study how relaxation dynamics of a poly-vinyl-acetate ultra-thin film is influenced by inorganic nano-inclusions of a layered silicate (montmorillonite).

Wave reflection in dielectric media obeying spatial Kramers-Kronig relations

open access: yes, 2015
In a recent work, S.A.R. Horsley and coworkers [Nature Photon 9, 436-439 (2015)] showed rather interestingly that planar dielectric media, for which the real and imaginary parts of the dielectric permittivity are related by spatial Kramers-Kronig (KK ...

All‐Dielectric Active Terahertz Photonics Driven by Bound States in the Continuum

open access: yesAdvances in Materials, 2019
The remarkable emergence of all‐dielectric meta‐photonics governed by the physics of high‐index dielectric materials offers a low‐loss platform for efficient manipulation and subwavelength control of electromagnetic waves from microwaves to visible ...

Condensation of the atomic relaxation vibrations in lead-magnesium-niobate at $T=T^*$

open access: yes, 2013
We present neutron diffraction, dielectric permittivity and photoconductivity measurements, evidencing that lead-magnesium niobate experiences a diffuse phase transformation between the spherical glass and quadrupole glass phases, in the temperature ...
