We’re talking of course about the air-dielectric variable capacitor, the tuning element for millions of radio receivers back in the day but now long ago replaced by much flimsier polymer ...

Finding high voltage capacitors can be tricky ... According to the post, there are 400 microns of dielectric and 600 microns air gap, so that’s a millimeter gap between each plate.

Excitingly, the nanosheet-based dielectric capacitor achieved a high energy density that maintained its stability over multiple cycles of use and was stable even at high temperatures up to 300°C.

Researchers have developed a dielectric film that has optical and electrical properties similar to air, but is strong ... every handheld device has hundreds of capacitors, which are dielectric ...
