Abstract
In order to design displacement resonant transducers in UHF-band, characteristics of shielded cylindrical dielectric resonators are investigated for the first higher order modes by means of the transverse resonance method of cascaded waveguides. The effect of the geometrical and electrical parameters of the structure on the displacement sensitivity and conductor Q-factor is examined for the $TE_{01\delta}$ mode and for higher order modes.
