About the Event

The focus of my research is on wave scattering in dense volumetric and layered random media. The goal is to use the microwave remote sensing technique to monitor land surfaces for water resources and global climate change. Towards this goal, I study the microwave scattering behavior of terrestrial snow, snow on sea ice, and the polar ice sheet. In snow remote sensing, I will discuss about the dense media radiative transfer (DMRT) theory and its applications at X-, Ku- and Ka- bands. I will also introduce newly developed full wave simulation techniques to deal with scattering and emission from layered snowpacks. The full wave approach readily applies to random inhomogeneities scattering and emission above a random rough surface. In polar ice sheet remote sensing, I will discuss a new instrument called ultrawide band software defined radiometer (UWBRAD) operating at 0.5 to 2.0GHz. The instrument has been flown over Greenland ice sheet twice in the year 2016 and 2017. I will report the campaign results and explain the underlying wave scattering physics that help to interpret the results. Here is a photo of Shurun taking data in the snow.


Shurun Tan received the B.Eng. and M.Eng. degrees in electrical engineering from the Southeast University, Nanjing, China, in 2009 and 2012, respectively, and the Ph.D. degree in electrical engineering from the University of Michigan, Ann Arbor, MI, USA, in Dec. 2016. From Dec. 2010 to Nov. 2011, he was a Visiting Student with the Department of Electrical and Computer Engineering, the University of Houston, Houston, TX, USA. From Sep. 2012 to Dec. 2014, he was a PhD candidate with the Department of Electrical Engineering, the University of Washington, Seattle, WA, USA. From Jan. 2015, he has been affiliated with the Radiation Laboratory, and the Department of Electrical Engineering and Computer Science, the University of Michigan, Ann Arbor, first as a PhD candidate, and recently as a postdoctoral research fellow since Jan. 2017. His research interests include electromagnetic theory, wave propagation and scattering in random media with applications in geophysical remote sensing of terrestrial snow, ice sheet, and vegetated land surfaces. He is also interested in high performance computing, and in wave propagation and scattering in periodic wave functional materials such as photonic crystals and metamaterials.
