Electromagnetic force Astronomers using three of the world's most powerful telescopes say they've found no change in one of nature's fundamental forces over the past 10 billion years. The study, ...

The electromagnetic force has gotten a little stronger, gravity a little weaker, and the size of the smallest "quantum" of energy is now known a little better. NIST has posted the latest ...

Electrical engineers at Duke University have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will ...

Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides. Gravity is ...

Introduction to electromagnetic waves in electrical engineering. Topics include: concepts of transmission lines, electrostatics and magnetostatics; Maxwell's equations for time-varying fields; ...

Recent advancements in artificial nanomaterials and structured optical fields have expanded the concept of chiroptical phenomena. However, chiroptical phenomena originate from complicated processes ...

Metamaterials that mimic the order in matters have opened an exciting gateway to reach unprecedented physical properties and functionality unattainable from naturally existing materials. The "atoms" ...
