Abstract: In this paper, we propose a hybrid PML (H-PML) combining the normal absorption factor of convolutional PML (C-PML) with tangential absorption factor of Mutiaxial PML (M-PML). The H-PML boundary conditions can better suppress the numerical… read more here.

DOI: 10.1080/17455030.2020.1734685
Abstract: According to the boundary conditions between two adjacent layers, a method for calculating the acoustic reflection coefficient of the layered ice-snow model is proposed, which is called the boundary condition method (BCM). Based on the… read more here.

DOI: 10.3233/thc-228019
Abstract: BACKGROUND: In endoscopic photoacoustic tomography (EPAT), the photoacoustically induced ultrasonic wave reflects at tissue boundaries due to the acoustic inhomogeneity of the imaged tissue, resulting in reflection artifacts (RAs) in the reconstructed images. OBJECTIVE: To… read more here.
