Evaluation:
Grading is C/NC. Students attending only the weekly seminar will receive 1 credit; those completing a project will receive 3 credits. Class projects will involve applying a Mie scattering code that will be provided by the instructor in MATLAB to a practical optical sensing problem.
Prerequisites: This seminar is designed for Graduate level Civil Engineering and Atmospheric Sciences students and others from engineering or natural sciences.
