This award will support collaborative research between Prof. George Jiracek of San Diego State University, and Dr. Art Raiche of the commonwealth Scientific and Industrial Research Organization (CSIRO), New South Wales, Australia. The investigators will work on the three-dimensional modeling of controlled-source electromagnetic radiation. The response of the earth when irradiated can yield important geological information, but modeling is necessary to enhance our interpretation of this information. Earlier work of the U.S. investigator will be extended to apply to inhomogeneous, irregular three-dimensional earth geometries. The project combines the expertise of the U.S. investigator in three- dimensional modeling using the Rayleigh-Fast Fourier Transform method, with that of the Australian investigator in Rayleigh scattering experimentation. The work has the potential to greatly facilitate minerals exploration, and would also facilitate the interpretation of data on electromagnetic groundwater EM response, toxic contaminant monitoring, and earthquake precursors.

该奖项将支持圣地亚哥州立大学的George Jiracek教授和澳大利亚新南威尔士州联邦科学与工业研究组织(CSIRO)的Art Raiche博士之间的合作研究。研究人员将致力于可控源电磁辐射的三维建模。地球在受到辐射时的响应可以产生重要的地质信息，但建模是必要的，以加强我们对这些信息的解释。美国研究人员的早期工作将扩大到适用于不均匀、不规则的三维地球几何图形。该项目结合了美国研究人员在使用瑞利-快速傅立叶变换方法进行三维建模方面的专业知识，以及澳大利亚研究人员在瑞利散射实验方面的专业知识。这项工作有可能极大地促进矿产勘探，还将有助于解释关于电磁地下水电磁响应、有毒污染物监测和地震前兆的数据。
