Abstract
This paper describes how to reduce spurious resonances which can take place in a resonator using guided waves above a Bragg mirror. These parasitics arise from overtone resonances as well as from higher order modes also excited by electrodes having inappropriate dimensions. In this paper, the influence of period and metalization ratio on the harmonic admittance of a resonator is studied.
