If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Abstract: Mass sensitivity of thickness-twist vibration modes in a rectangular plate piezoelectric resonator of 6-mm crystals are obtained from the three-dimensional equations of linear ...

Abstract: This paper presents the design of a broadband frequency selective surface (FSS) with a high rectangular coefficient based on lumped capacitance loading. The proposed structure comprises two ...

THE higher overtones of vibrating plates sometimes combine when it so happens that the periods of two or more of them are very nearly equal. This phenomenon, which is of academic rather than of ...
