Abstract: In the context of a recoil damping analysis, we have designed and produced a membrane resonator equipped with a specific on-chip structure working as a \”loss shield\” for a circular membrane. In this device the vibrations of the membrane, with a quality factor of 10(7), reach the limit set by the intrinsic dissipation in silicon nitride, for all the modes and regardless of the modal shape, also at low frequency. Guided by our theoretical model of the loss shield, we describe the design rationale of the device, which can be used as effective replacement of commercial membrane resonators in advanced optomechanical setups, also at cryogenic temperatures.
