To achieve this, a time-domain equivalent circuit simulation platform for PMUTs is developed to quickly obtain and analyze the air-coupled PMUTs response. This platform facilitates to fast obtain the ring-down times for different excitation signals and allows continuous adjustment of parameters for the offset signal waveform. The optimal offset signal waveform is then identified by comparing ring-down times generated across various parameter configurations of offset signals in simulation. The effectiveness of these optimized offset signals achieved through the proposed method is confirmed experimentally with different driving signals. For example, for a PMUT cell with a radius of 360 μm, the ring-down time is decreased by at least 85.49 % with the obtained optimal offset signal for short-period driving signals, while the −6dB bandwidth of the PMUT is increased by more than 3.85 times with the obtained optimal offset signal for long-period driving signals. By suppressing ring-down, the proposed method minimizes the blind zone, sharpens the echo envelope, and enhances positioning accuracy for ultrasound applications. Furthermore, the developed simulation platform has significantly improved the efficiency of time-domain simulations for PMUTs research, providing a solid foundation for future system-level optimizations and studies on PMUTs applications.</div></div>","PeriodicalId":23522,"journal":{"name":"Ultrasonics","volume":"155 ","pages":"Article 107711"},"PeriodicalIF":3.8,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The low acoustic attenuation characteristics of ZFW is particularly well-suited for defect detection of highly attenuative materials. In our previous study, large detection depths in high-density polyethylene (HDPE) have been demonstrated using ZFW. However, in practical engineering applications, defect detection in HDPE with irregular surfaces is hindered by limitations in complex propagation path and low coupling efficiency. To address this issue, using ZFWs generated by the propagation of high-frequency ultrasonic waves, a water immersion SAFT imaging method is proposed for HDPE with irregular surfaces. The proposed method, based on the priori knowledge of geometric interface between water and the measured HDPE with irregular surface, utilizes the Snell’s law to get the propagation paths of the ZFWs. The propagation time of ZFW in water and HDPE is computed using these paths, through which its time-of-flight is obtained. The time-of-flight is subsequently utilized to calculate the intensity of each pixel. Finally, the normalized imaging results are finally generated after iterative computations across all scanning points. Experimental results show that the proposed method is capable of detecting side-drilled hole defects with a diameter of 1 mm and a longitudinal depth of approximately 100 mm in HDPE with irregular surfaces including incline surface, convex surface, and concave surface. These findings validate the effectiveness of the proposed method in detecting defects in highly attenuative materials with irregular surface, demonstrating its potential as a valuable tool for non-destructive testing.</div></div>","PeriodicalId":23522,"journal":{"name":"Ultrasonics","volume":"155 ","pages":"Article 107703"},"PeriodicalIF":3.8,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we derive and validate a set of transmit–receive conditions that ensure artifact-free PSFs without unnecessary computational overhead. We demonstrate that by appropriately selecting the plane-wave steering angles, transmit pulse cycle count, and receive aperture (F-number) in relation to the pixel spacing, high spatial frequencies in the PSF remain within the Nyquist limit for all imaging depths. Through a series of simulations, wire phantom tests, and custom flow phantom experiments, we compare undersampled, oversampled, and balanced parameters. The balanced configurations, where the maximum frequency of the PSF matches the beamforming grid, consistently mitigate aliasing artifacts, eliminate grid-like patterns, and preserve microbubble trajectories under sub-pixel translations. In a flow phantom study, we further confirm that ULM images obtained with these optimized settings retain fine details without incurring the substantial computational costs of an overly fine sampling grid. Our findings highlight the importance of analysing PSF bandwidth in both lateral and axial dimensions and offer a straightforward method to align transmit pulse width, receive aperture, and grid spacing.

The novelty of this paper is found in the energy calculations and the consideration of higher-order modes for accurately describing the transmission and reflection coefficients at waveguide transitions. A 2D axisymmetric Finite Element Method (FEM) is used to calculate these coefficients based on the modal energy of propagating modes across different frequencies. The influence of geometrical and material properties, along with modal density, is examined numerically. Results demonstrate that optimal transmission occurs when the wavenumber ratio of propagating modes in connected waveguides is an integer, leading to effective coupling. Experimental validation on steel rods with diameters from 4 mm to 0.8 mm shows strong agreement with numerical results. It is observed that the L(0,1) mode around 1 MHz is the most suitable mode for efficient transmission between the waveguides. In contrast, the higher-order modes (L(0,2) around 1.25 MHz, L(0,3) between 1.3 and 1.5 MHz, and L(0,4) from 2.25 MHz) exhibit weak or irregular transmission, with more pronounced reflection behaviors, indicating that they are not optimal for efficient transmission in this configuration.
