Abstract: This article investigates the influence of high-energy secondary electrons on a Ka-band TM03 relativistic backward-wave oscillator (RBWO) using the particle-in-cell (PIC) simulation code ...

This video explains overlapping waves on a string using concepts from AP Physics 1. We explore superposition, interference, and how wave pulses interact when they meet, with clear visuals and ...

Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can ...

One of the most influential science studies of all time started with a modest minicomputer, some simulated boxes of water molecules, and a grand vision for computer-aided chemistry. The year was 1982.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Balmoral Comtec recently invested more than $1.3m in a new wave and current simulation center, a facility that will be used to help develop Balmoral’s own subsea technologies, including its HexDefense ...

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on ...

As a physics professor and gamer, I’m always on the lookout for amazing science hidden in popular video games. When I started playing Fortnite in 2018, a small mathematical detail caught my attention.

Add a description, image, and links to the phet-simulations topic page so that developers can more easily learn about it.

Could invisibility cloaks become a reality? New research brings this science fiction concept a step closer, with a breakthrough software package that simulates how waves interact with complex ...
