Description
Nine authors, led by Weijia Zhang, report a 2024 way to test what is inside a sealed liquid without touching it, using microwave radar. Older light based tests have limits for this task. Radar bounce strength shifts with the mix of a liquid, since each part answers the waves in its own way.
Trials showed a strong link between sour parts in a liquid and how much signal bounces back. The method hit about two percent error in tests. It could tell apart drinks and acid mixes at unlike strengths. The team sees uses in food and factory checks where opening a pack is not wanted.
