# Full Wave and Asymptotic Solution Methods

The Solver includes multiple frequency and time domain solution methods. True hybridisation of some of these methods enables efficient analysis of a broad spectrum of electromagnetic problems. You can also use more than one solver method for cross-validation purposes.

- Full wave frequency domain solution methods:
- MoM (method of moments)
- FEM (finite element method)
- MLFMM (multilevel fast multipole method)

- Full wave time domain solution methods:
- FDTD (finite difference time domain)

- Asymptotic solution methods:
- PO (physical optics)
- LE-PO (large element physical optics)
- RL-GO (ray launching geometrical optics)
- UTD (uniform theory of diffraction)
