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 ...
Mass sensitivity of thickness-twist modes in a rectangular piezoelectric plate of hexagonal crystals
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 ...
