When the gas is not ionized, the antenna element ceases to exit. ... Measurements indicate that the plasma antenna yields a return loss over 10 dB in the 2.23 GHz to 2.58 GHz frequency band.

Each plasma antenna array would then be integrated with a Wi-Fi router to provide large-scale, ... Jan. 24, 2024 — Two research groups design a plasma (an ionized gas) ...

Plasma antennas disappear when shut off. Skip to main content. Scientific American. ... and the resulting cloud of ionized gas would then strongly propagate electromagnetic signals from a special ...

When English physicist William Crookes first discovered plasma in 1879, he did not propose any use for the stuff. Crookes found that he could make gas behave differently than other forms of matter ...

In this process, a jet of plasma or ionized gas is ejected at high speeds, which melts and subsequently removes unwanted parts of materials from electrically conductive workpieces such as metals.

It has to be a low-energy plasma with very little ionization. This keeps the temperature low so that the delicate integrated circuits are not damaged. Furthermore, the ionized gas must be generated ...

The microwaved grape trick also shows their promise as alternative microwave resonators for quantum sensing applications, according to the authors of this latest paper.
