Course Outline

  1. Acousitc wave equation and its solution (2 Lectures)
  2. Concept of Stress/strain (2 Lectures)
  3. Elastic wave formulation and its solution (2 Lectures)
  4. Energy partitioning for normal and oblique incidence (1 Lecture)
  5. Green function and related theorems ( Uniqueness, Representation, Reciprocity, Lippman-schwinger, etc.) (2 Lectures)
  6. Seismic sources representation
  7. Concept and mathematical description of Imaging methods- Diffraction summation, Kirchoff method, RTM and FWI (3 Lectures).
  8. Finite difference modeling (2 Lectures)
Optional
Seismic sources and receivers charateristics,
2D/3D Acquisition,
... (yet to include)

Grading Policy

Grade assessment is based upon- Attendance (10%), Assignment (20%), Final exam (70%).
All the assignments must to be handed over before the due dates. Late submission will face a penalty of 20% for each delayed week. If the assignments are found to be copied (among student/from internet) it will be graded as zero.
