PML (Perfectly Matched Layers)
The perfectly matched layer (PML) is a domain or layer (sometimes called sponge layer) that is added to an wave model to mimic an open and nonreflecting infinite domain. It sets up a perfectly absorbing domain as an alternative to nonreflecting boundary conditions.
More math detail can be found here.[1]
Symmetry
The symmetry condition can effectively reduce the computation of simulation. The rule of symmetry is mathematics thing. So, let me just know the result.
Name | Name in Lumerical | Name in Tidy3D |
---|---|---|
Perfect Electrical Conductor (PEC) | Anti-Symmetric | odd, -1 |
Perfect Magnetic Conductor (PMC) | Symmetric | even, 1 |
