Abstract: Abstract Quality factor (Q) and frequency-quality factor (Qf) of prestressed membrane resonators are enhanced by topology optimization. The optimization targets the fundamental mode which is more easily identified in physical experiments compared to high-order modes… read more here.

Abstract: We report that Hybrid membrane resonators (HMRs) made of a decorated membrane resonator backed by a shallow cavity can function as Helmholtz resonators (HRs) when mounted on the sidewall of a clear waveguide for air… read more here.
