Researchers invented a novel method to measure the permittivity of insulators 100 times more accurately than before. This technology is expected to contribute to the efficient development of sensitive ...
As wireless system frequencies increase and wavelengths decrease, RF designs present many new challenges. Among them is the need for dimensional and parameter stability, as changes of even a fraction ...
Three RIKEN researchers have created a liquid whose response to an electric field can be tuned over the largest range of any known material 1. The fluid could find use in various applications ...
A new technical paper titled “Characterizing the Broadband RF Permittivity of 3D-Integrated Layers in a Glass Wafer Stack from 100 MHz to 30 GHz” was published by researchers at NIST. “We present a ...
A new technical paper titled “The van der Waals Gap: a Hidden Showstopper in Semiconductor Device Scaling” was published by ...
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) ...
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 ...
Hypergap materials reveal a second transparent region above the bandgap, overturning assumptions about optical limits and enabling low-loss light control, wavelength conversion, and new photonic ...
One evening quite a few years ago, as I was driving through my hometown I saw the telltale flashing lights of the local volunteer fire department ahead. I passed by a side road where all the activity ...
