An oscillator circuit is proposed that simultaneously excites and tracks two harmonic resonances in a piezoelectric resonant sensor that, in particular, can be a quartz crystal resonator (QCR) sensor. By probing the resonator at two harmonic modes at the same time, enhanced sensing capabilities can

## Abstract A novel approach for modeling the discontinuities of transmission lines such as conductors with bends and varying size is proposed. The effect from the discontinuities is incorporated in the per‐unit‐length parameters of nonuniform transmission‐line equations. For canonical problems, ou
