The acoustoelastic effect relates the change in the speed of an acoustic wave travelling in a solid, to the pre-stress of the propagation medium. In this work the possibility of assessing nondestructively the stress status in metal sheets, by using the acoustoelastic effect, is ... Mehr lesen
A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... Mehr lesen
The simulation of a large acoustic cylindrical antenna made of numerous identical transducers is very often out of reach in terms of computational cost. Therefore the usual design procedure consist in optimizing the transducer standing alone, either in free field arrangement or sitting ... Mehr lesen
为实现超声导波对零部件的遍历检测，需研究超声导波相位模态控制与空间聚焦双相控技术。本文建立了超声导波阵列传播模型，推导得到二维阵列相位模态控制与空间聚焦双相控方法，在有限元软件COMSOL中运用固体力学物理场接口，建立铝板超声导波二维阵列聚焦传播模型，通过对各阵元添加不同的延时控制，实现激励模态控制与空间聚焦仿真，获得激励模态下铝板中超声导波传播的位移场分布，为超声导波阵列换能器的研制以及聚焦实验研究提供了有力依据。 Mehr lesen
Ultrasound is a promising green technology for the advanced oxidation process (AOP) since it adds no chemicals to the treated water. In this paper, COMSOL Multiphysics® was used as a tool to design and characterize an ultrasound irradiator with multi-stepped configuration, which aims to ... Mehr lesen
In this paper we present a method to mitigate the effect of thermally-induced noise in Micro-Electro-Mechanical Systems (MEMS) through a force feedback circuit. Inherent noise-induced vibrations, which would be inconsiderable in macro scale, are considered as a limitation in micro- and ... Mehr lesen

传统声表面波（SAW）滤波器技术存在Q值低（＜1000）和频率随工作温度漂移的特性，已经难以满足频段越来越拥挤的5G时代射频终端对滤波器的要求，因此，传统的SAW滤波器必须向具备高频率-温度稳定性的温度补偿型SAW（TC-SAW）滤波器发展。鉴于SiO2层与压电层具有相反温度弹性的特性，且该工艺比另一种键合温补方法简单、成本低，是目前国内外声表厂家广泛采用的一种温补方式。 对该种TC-SAW谐振器进行COMSOL建模仿真，研究SiO2层、指条层厚度对SAW波导的影响，以及材料参数和结构尺寸与SAW滤波器频率温度系数（TCF）及机电耦合系数之间的关系 ... Mehr lesen
