Giovanni D’Amore discusses approaches to characterising both dielectric and magnetic materials using impedance analysers and specialist fixtures. We are used to thinking about technological progress ...
JuanHinojosa obtained a Ph.D. degree (Doctorat d'Université)in electronics from the University of Lille, France, in 1995. Hisresearch activities have focused on the development of measurementbenches ...
Homogeneous composites, or metamaterials, made of dielectric or metallic particles are known to show magnetic properties that contradict arguments by Landau and Lifshitz [Landau LD, Lifshitz EM (1960) ...
US researchers have for the first time pushed the limits for negative-index metamaterials to infrared wavelengths. Researchers at Purdue University, Indiana, have created a negative-index metamaterial ...
If you think about dielectric properties at all, it is probably in the context of school physics experiments on charge storage, or perhaps the way in which the choice of dielectric materials ...
An interface between media with different helicities (red and blue curly arrows) supports zero-helicity linearly polarized surface modes (green arrow). (Credit: Konstantin Bliokh) Maxwell’s ...
Physicists in Germany have made a new type of photonic crystal by fine-tuning the magnetic, rather than the electric, properties of a material. Photonic crystals are nanostructured materials in which ...
