报告人简介：
Pavel S. Petrov于2009年获得伊尔库茨克州立大学(Irkutsk State University)数学专业的硕士学位，于2012年获得太平洋研究所(Il’ichev Pacific Oceanological Institute)理论物理专业的正博士学位。自2012年至今，Pavel S. Petrov博士在太平洋研究所担任研究员职位，同时在远东联邦大学(Far Eastern Federal University)兼任副教授职位。期间他两次以洪堡学者奖学金获得者的身份前往德国高校进行访问和进修，并在以色列海法大学Boris Katsnelson教授处做过短期博后。由于在三维声传播模型方面发表了一系列高质量文章，太平洋研究所于2017年授予Pavel S. Petrov博士以“声学与海洋研究领域年轻科学家伊利切夫奖”。
Pavel S. Petrov博士的研究专长包括声传播、吸收与散射、计算海洋声学、波动过程数学建模、渐进方法等。Pavel S. Petrov博士尤其在三维海洋声传播及其应用方面颇有造诣，他编写的多项三维声场计算代码已上传至水声领域著名开源网站Ocean Acoustics Library，可供免费使用。
报告简介：
The lecture provides an overview of existing numerical approaches to the artificial domain truncation in the parabolic equation theory. This technique is important for the solution of propagation problems in various applications including underwater acoustics, radiowaves theory, geophysics, optics etc., since in many cases the domains where the wavefields must be computed have no physical boundaries. Exisiting approaches include artificial/absorbing/transparent boundary conditions, perfectly matched layers, and complex absorbing potentials. Each of them has certain strengths and weaknesses, and the choice of suitable technique often depends on the application field. In our lecture we attempt provide a comprehensive overview of existing approaches and to show several practically important examples.
