High-power high-frequency (HF) radio waves transmitted from ground-based facilities interact nonlinearly with ionospheric plasma to alter its electron density, temperature and structural properties.

Traditionally, experimental geospace research, including probing of the atmosphere, the ionosphere, and the magnetosphere (AIM), has been conducted passively (i.e., no controlled input/response ...

Shaped by eddy-wave interactions, the high-frequency motions in the ocean surface mixed layers follow a universal energy ...

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.

As high-frequency circuit design evolves, the gap between theoretical models and practical application is narrowing thanks to recent computational breakthroughs. A 2024–2025 surge in co-simulation ...
