When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...

Antennas come in many shapes and sizes, with a variety of characteristics making them more or less suitable for various applications. The average hacker with only a middling exposure to RF may be ...

As researchers around the world race toward the realization of 6G wireless communication systems, the need for antennas that can dynamically adapt to ever-changing signal environments has never been ...

Three-dimensional magnetic vortices have recently been discovered. Vortex states are potential antennas for the ultrafast, wireless data transmission of tomorrow. hree-dimensional magnetic vortices ...

Non-Foster circuit design offers a transformative approach to overcoming the intrinsic limitations of traditional passive matching networks. By utilising active elements to generate negative impedance ...
