REO-USA has introduced the 400V three-line CNW933 sinusoidal filter range as an equally robust yet more cost effective solution to shielded cables. The cost of cables is rising in manufacturing as the result of the need for lengthy shielded cable to tackle attenuation and electromagnetic compatibility (EMC) issues. Compounded by increasing commodity prices, this is leading … [Read more...]

Sub-Wavelength Images Could Be Made at Radio Frequencies
Scientists have released new theoretical and experimental work that suggests an innovative method using optical wavelengths to overcome certain restrictions on electric field evaluation. Current methods of mapping electric fields at radio frequencies employ certain metallic structures such as dipoles, probes and reference antennas. These structures, however, must be roughly … [Read more...]
Researchers Predict Electrical Resistivity of Metals Under Extreme Pressures
A study recently published in the Proceedings of the National Academy of Sciences (PNAS), headed by scientists at Rensselaer Polytechnic Institute (RPI), has demonstrated how subjecting metals to intense pressures could lower their electrical resistance, which could potentially lead to increased speed and performance in many technologies. Strain engineering, or the … [Read more...]
