B. Advanced electromagnetic methods
- Inverse Electromagnetic Problems — scattering forward models, inverse problems, regularization and identifiability.
- RF Direction Finding & Geolocation — AoA, wrapped phase, TDOA/FDOA, subspace methods and calibration.
- Advanced Antenna Metrology — probe-corrected near-to-far transforms, gain and uncertainty.
- Multiphysics EM–Thermal–Structural Simulation — coupled electrical losses, temperature and deformation.
- Inside a Scientific Instrument — three end-to-end studies: Cassini MAG, Webb infrared detectors and DSN tracking.
C. Reproducible Python exercises
These examples use NumPy and Matplotlib and require no proprietary electromagnetic simulation tool or RF hardware:
| Script | Observable |
|---|---|
| magnetic_boom_model.py | Dipole contamination versus magnetometer boom distance |
| coherent_timing_demo.py | Relative sample phase, frequency drift and channel delay |
| doa_array_demo.py | Calibrated array phase and Bartlett direction finding |
| radiometry_photon_budget.py | Planck radiance integrated through an infrared detector passband |
Run with Python 3 plus NumPy and Matplotlib; replace synthetic observations with calibrated measurements when moving to real equipment.
