These limitations can be addressed through the implementation of mode conversion techniques. However, an expanded radiation area may also result in reduced acoustic radiation intensity. To mitigate this issue, this study proposes an Acoustic Black Hole Ultrasonic Radiator (ABHUR) designed to enhance ultrasound intensity and thereby achieve high-efficiency radiation. The proposed ABHUR comprises a Bolted Langevin-type Transducer (BLT) and a Curved Acoustic Black Hole (CABH) ring. A theoretical model, based on the transfer matrix method, is developed to analyze the in-plane vibrational behavior of the CABH ring, and its validity is confirmed through Finite Element Method (FEM) simulations. The underwater vibrational and sound field distribution properties of the ABHUR are investigated using FEM and compared with two alternative radiators employing longitudinal-bending (L-B) and longitudinal-radial (L-R) modes. Owing to the unique properties of the Acoustic Black Hole structure (ABHs), which amplify bending wave amplitudes and concentrate energy, the ABHUR operating in L-B mode demonstrates superior ultrasound intensity. Furthermore, a prototype of the ABHUR is fabricated, and a series of three experiments are conducted to validate the operational feasibility of the proposed system.</div></div>","PeriodicalId":23522,"journal":{"name":"Ultrasonics","volume":"151 ","pages":"Article 107630"},"PeriodicalIF":3.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631971","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}

However, the accuracy of existing reconstruction techniques heavily depends on the precision and completeness of time–frequency (TF) ridge extraction. To address this challenge, this paper proposes a TF energy segmentation reconstruction method without relying on complete TF ridge extraction, as traditionally required. This approach introduces an adaptive noise variance estimation Bayesian filter to extract the TF ridges under unknown noise distribution, particularly in regions where TF ridges intersect or overlap. By using the extracted TF ridges as references, the energy segmentation method directly separates and reconstructs UGW modes from the TF representation even when the extracted TF ridges are incomplete. This is because the proposed method can automatically retrieve the energy of each mode with a region growing algorithm from the time domain and frequency domain so that both modes with rapidly changing instantaneous frequency or group delay can be recovered, while the traditional method can only separate modes from a single domain. Numerical simulations and photoacoustic-guided wave experiments validate the effectiveness of the proposed method, achieving reconstruction accuracies of 96.9% and 92.5% for the simulated and experimental signals, respectively.</div></div>","PeriodicalId":23522,"journal":{"name":"Ultrasonics","volume":"151 ","pages":"Article 107635"},"PeriodicalIF":3.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631970","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}

Hence, a novel push-pull slotted tube ultrasonic transducer (PSTUT) based on longitudinal-bending mode conversion has been proposed. The PSTUT is composed of four key parts: two sandwich transducers, two stepped horns, two end caps, and a slotted tube radiator. By applying push-pull longitudinal excitation, the caps produce longitudinal bending vibration, while the arc-shaped plates produce radial bending vibration, capable of achieving efficient, uniform, and omnidirectional ultrasound radiation. Based on the principle of electromechanical analogy and the theory of Timoshenko beams, the electromechanical equivalent circuits of the uniform beam in bending vibration and the PSTUT in coupled vibration are established. The frequency response of the PSTUT is validated by the finite element method simulations and experiments. The vibration analysis demonstrates that adjusting the size of the circular slotted tube radiator can control both the range and intensity of radial radiation. Simulated and experimental results show that the PSTUT exhibits satisfactory 3D-omnidirectional radiation capability and improved sound field uniformity in water. The proposed PSTUT offers a promising solution to overcome the bottleneck in ultrasonic liquid treatment technology.</div></div>","PeriodicalId":23522,"journal":{"name":"Ultrasonics","volume":"151 ","pages":"Article 107636"},"PeriodicalIF":3.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642201","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 modality, SOS images are reconstructed with an iterative process to match the measured time-of-flights and the ones predicted by Eikonal equation solved with the fast marching method (FMM). The Eikonal equation is meant to be applied in SOS heterogeneous media and its evaluation with FMM is an computational expensive process. However, in USCT, the object is placed in a homogeneous coupling medium. Thus, the acoustic environment is formed by two parts, the homogeneous background (coupling medium) and the heterogeneous object. In this work, we leverage this strong <em>a priori</em> information and propose a method to accelerate SOS image formation for bent-ray tracing USCT. We show that, given the boundary information of the object, Eikonal equation only needs to be evaluated in a limited area covering the object. For that, the partial FMM and the associated ray-tracing strategy are proposed to reduce the computational cost of the forward modeling. We also managed to restrict image reconstruction area inside the object for improved convergence rate of the optimization. Both the simulation and phantom imaging experiments with ring transducer arrays demonstrated that the proposed method reduces the reconstruction time in an object size dependent manner. For the object occupying 20.3% to 56.3% of the image field of the ring array, we observed 30.1%–61.9% reduction in image reconstruction time without sacrificing the image quality, compared to classical method.

During the LPBF process, ultrasonic signals are affected by thickness variations of specimens. This study analyzes the transmission of ultrasonic waves at different thicknesses and the variations in wave types. Realistic AM surface roughness data were incorporated into the simulation model to generate ultrasonic signals at various thicknesses. Subsequently, experimental studies were conducted. The research findings demonstrate that the Lamb wave characteristics are most prominent when the thickness is 0.2 mm. As the thickness increases, there is a gradual attenuation of the Lamb wave dispersion, accompanied by the emergence of surface wave features. The Lamb wave behavior diminishes as the thickness exceeds 3.021 mm, and surface wave, transverse wave, and longitudinal wave become more prominent. The dispersion curves were derived using the f-k method, and the thickness of LPBF Ti-6Al-4 V specimens smaller than 1 mm is precisely inversed based on dispersion curve. The verification experiments demonstrate that the model solution for thickness has a relative error of less than 5 %.

Firstly, the Lamb wave signal is excited and received in the real aircraft cutting section. The collected signal is processed in one-dimensional (1D) by extracting the damage index, and two-dimensional (2D) by transforming it into the Gramian angular field (GAF), respectively. Then a deep learning model with multi-dimensional feature fusion is established, which includes two neural network branches, namely 1D branch network and 2D branch network. Among them, 1D branch network includes multi-scale convolution Inception-v1 module and Bi-directional long short-term memory (BiLSTM) layer, and 2D branch network includes continuous convolution module and BiLSTM layer. The extracted 1D and 2D damage information is fused and learned to further enhance its spatial and temporal representation ability. Finally, the transfer research across geometric sensor arrays is attempted. The test results show that this method effectively locate and quantify the single-source offset damage and multi-source cumulative damage in the aircraft cutting section.
