Electromagnetic Wave Scattering Modeling and Algorithm Development

In this project, I utilized MATLAB to simulate the interaction of electromagnetic waves (Normalized Radar Cross-Section (NRCS)) with clean and oil-contaminated sea ice in the C-band at 5.5GHz for VV and HH polarizations. Electromagnetic wave scattering and wave modeling was an important factor in this study. The different scenarios of scattering including surface and volume scattering based on the operational frequency needed to be considered for this study. The paper title is "Modeling Normalized Radar Cross-Section of Oil-contaminated Sea Ice with Small Perturbation Method" and can find the paper here.

In this project, I considered clean sea ice as a complex medium consists of pure ice as a background and brine pockets as inclusions. Next, I modeled clean sea ice with the five existing dielectric mixture models including Linear, Refractive, Cubic, Tinga Voss Blossey (TVB), and Polder Van Santen De Loor (PVD). To simulate the NRCS of clean sea ice, I supposed that the scattering is only due to the surface scattering and volume scattering due to the low penetration depth of electromagnetic waves into sea ice at 5.5GHz can be neglected.

The next step was to simulate the NRCS of oil-contaminated sea ice.

For this purpose, I considered oil-contaminated sea ice a mixture of clean sea ice with oil pockets embedded within the medium. For modeling purposes, I used the same five existing dielectric mixture models as the clean sea ice models.

The last part of this project was to compare the NRCS simulation results of clean and contaminated sea ice.

The outcome of this work was one IEEE conference paper:

One IEEE Journal Paper and one conference proceedings (IEEE ANTEM). These papers can be found in my google scholar profile.

The next publication from this topic is to compare the simulation results with the actual measurements.

I am still working on further publications based on the available results (both simulations and actual measurements) of my study. I will update this page as soon as the current paper that I am working on gets published.
