Where the Solvers Apply Scattered or Total Field Formulations
Scattered Field Formulation
- Monostatic/bistatic RCS of finite scatterers
- Frequency Selective Surfaces (FSSs)
Total Field Formulation
- Monostatic/bistatic RCS of infinite scatterers
- Frequency Selective Surfaces (FSSs)
- When near/far field Link is involved
- EMC/EMI problems
For Scattered Field Decomposition
It is known in the whole domain.
In summary, scattered field descriptions apply:
- Environment material other than vacuum
- Inhomogeneous magnetic material
- Special treatments on
- Ports
- Impedance BCs
- PMC
Total Field Description: Usual Approach
When the incident field is known, everywhere, the solvers take the usual approach. Both E and H jump with n x Einc and n x Hinc on the interfaces, respectively.
Total Field Description: Unusual Approach
In this case, the incident wave is just on known on the surface. Both E and H jump with n x Einc and n x Hinc on the outer surface respectively.
Total Field Description: Space Port Concept
The Radiation Boundary Condition is treated as a space port. The field is decomposed just on the surface of the space port.
