Coatings
A coating can be applied to any wires or to both sides of a conducting face.
The following must be true when adding a coating to a face:
- One side must have free space.
- The other side must have free space or PEC.
The following coating thickness requirements apply when using the MoM / MLFMM, PO or RL-GO solution
methods:
Solution Method | Coating Thickness Requirement | CO Card Equivalent |
---|---|---|
MoM / MLFMM | Both electrically thin and geometrically thin | Electrically thin surface coating |
MoM / MLFMM | Electrically thick, but geometrically thin (single layer). Note:
|
Dielectric / magnetic surface coating (single layer) |
PO | Electrically thick, but geometrically thin | Dielectric / magnetic surface coating |
RL-GO | Both electrically thick and geometrically thick | Dielectric / magnetic surface coating |
Note: A geometrically thin coating must be thin relative to the triangle size
(and as a result also to the free space wavelength) as well as the curvature radius
of the surface.
