FR4 is FR4, right? For a lot of PCB designs, the answer is yes — the particular characteristics of the substrate material don ...

THE growth of barium titanate single crystals and the ferro-electric behaviour of their pseudocubic modification have been described earlier 1, 2, and more detailed data can now be given.

INVESTIGATING the electric properties of printing inks, it was observed that the dielectric constant of an ink depends on the time it stands undisturbed in the measuring condenser. For dielectric ...

A scalable, low-cost device that can generate high-power terahertz waves on a chip, without bulky silicon lenses.

Materials are known to interact with electromagnetic fields in different ways, which reflect their structures and underlying ...

Electromagnetic metamaterials with negative physical parameters such as negative dielectric constant and negative magnetic permeability have attracted widespread attention in the academic community.

Scientists have known about terahertz waves for years. Their unique properties suggest that these waves could enable high-bandwidth communication, ultra-fast data transfer, advanc ...

One way to generate terahertz waves is with a CMOS chip-based amplifier-multiplier chain that increases the frequency of ...

Here, however, we concentrate on another key element of organic FETs, namely, the dielectric layer that separates the transistor active material ... To evaluate the electrical stability of the ...
