H-Shaped Radial Phononic Crystal for High-Quality Factor on Lamb Wave Resonators [PDF]

Sensors, 2023
In this paper, a novel H-shaped radial phononic crystal (H-RPC) structure is proposed to suppress the anchor loss of a Lamb wave resonator (LWR), which has an ultra-high frequency (UHF) and ultra-wideband gap characteristics. Compared to previous studies
