Plasma made of microwave: the secret of the spraying grapes!

A research team from Macquarie University has succeeded in explaining the fascinating phenomenon that occurs when cut grapes in the microwave create plasma bleat. In the future, the special property of the grapes could contribute to the development of more efficient quantum sensors, such as "https://www.spektrum.de/news/wie-weintraße-die-die-fehnbeit-faehnkeit-von- Quantensors-Sensors-betten/2248673" Class = "Source_1"> Spektrum

The experiment shows that grapes reinforce magnetic fields, which makes it particularly interesting for quantum sensor applications. In order to observe this phenomenon, the team placed a quantum sensor on a glass fiber between two grapes, with green laser light brought the defect centers to red lights. Surprisingly, it turned out that the magnetic field of the microwave radiation was twice as strong.

resonance effect and plasma development

In addition, researchers have examined why grape halves in the microwave spray sparks and form plasma. The results show that it is not the electrical connection between the grape halves, but a resonance effect of the microwave radiation is responsible for the development of the plasma. At the contact points of the grape halves, a hotspot forms that concentrates and generates the plasma, such as scinexx emphasized.

In the experiment, a grape was cut so that a thin cutting connects both halves. It turned out that plasma can also be created without the skin bridge; The mere touch of the objects is sufficient. The findings from this study could have far -reaching applications in the development of electronic devices and antennas.
