System uses directional antennas and high‑power RF amplifiers for highly targeted electromagnetic warfare.

After decades of hunting, physicists still don’t know what makes up most of the universe’s matter. Now they need to cast a wider net.

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better ...

Some innovations in physics come from entirely new technologies, others from fresh theoretical insights. Others still take shape by bringing together existing tools in new ways, working out how to ...

This paper presents the optimization performance of non-uniform linear antenna array with optimized inter-element spacing and excitation amplitude using Particle Swarm Optimization (PSO). The aim of ...

Abstract: This study investigates the crosstalk suppression in small-pitch array high-energy particle (for example, alpha and electron) detectors. As for photodetector arrays, crosstalk between pixels ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Light scattering has long stood as a cornerstone technique in the characterization of particles across a wide range of scientific disciplines. From pharmaceuticals to food production, and from ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.

The original version of this story appeared in Quanta Magazine. On a quiet pandemic afternoon in 2021, Zhiyuan Wang, then a graduate student at Rice University, was alleviating his boredom by working ...

Researchers have developed a novel high-energy particle detection instrumentation approach that leverages the power of quantum sensors -- devices capable of precisely detecting single particles. To ...
