Determination of Practical Harmonic Levels
Well we are still waiting to see if borrowing 3D EM software is on the cards. I should know soon, one way or the other. I hope it happens, but for now let’s keep holding off on Elephant #3, ‘Fixing the Broken Automotive Test Fixture,’ In the meantime, we can continue the engineering approach on determining a practical level of harmonics in RF immunity for Elephant #2, … [Read more...]

Researchers Develop ‘Snake-Like’ Flexible Metamaterial Absorber
Korean researchers have developed a flexible “snake-shaped” metamaterial absorber with the ability to suppress electromagnetic radiation. Scientists have studied metamaterials since the late 19th century, when artificial dielectrics were developed just after World War II. These artificial materials are specially engineered to affect electromagnetic radiation, sound or seismic … [Read more...]
Scientists Investigate ‘Quantum Glue’ Trigger for Superconductivity
Physicists at the University of Illinois at Chicago have identified the “quantum glue” that binds electrons together to evoke superconductivity in a crucial step towards the creation of high-speed energy transport methods that conduct electricity without current loss. The new research, published online in the Proceedings of the National Academy of Sciences, is a collaboration … [Read more...]
New Single-Photon Optical Transistor Could Lead to Faster Data Transmission
Using an ultracold quantum gas, researchers at the Max Planck Institute of Quantum Optics in Germany have created a new kind of transistor-like optical amplifier that allows for a twentyfold amplification of single-photon signals. Although fiberoptic technology has helped speed along data transmission and telecommunications in general, researchers have hoped to find another … [Read more...]
