Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics ...

In this paper, a metamaterial aperture for generating electromagnetic vortex waves with frequency-diverse dual-mode orbital angular momentum (OAM) in the X-band (8 GHz–12 GHz) is designed. The ...

We present a fully telemetric strain sensor concept based on a novel millimeter-wave metamaterial and show the experimental proof of concept. The metamaterial consists of a single layer of copper ...

The pursuit for efficient nanoparticle trapping with low powers has led to optical tweezers technology moving from the conventional free-space configuration to advanced plasmonic systems. However, ...
