Overview of QPMS command line utilities
|
|
=======================================
|
|
|
|
The utilities are located in the `misc` directory. Run the
|
|
utility with `-h` argument to get more info.
|

Rectangular and square 2D lattices
|
|
----------------------------------
|
|
|
|
These scripts deal with simple 2D rectangular lattices,
|
|
finite or infinite, one scatterer per unit cell.
|
|
\f$ D_{2h} \f$ or \f$ D_{4h} \f$ symmetric adapted bases
|
|
are used where applicable.
|
|
|
|
### Finite lattices
|
|
|
|
* `finiterectlat-modes.py`: Search for resonances using Beyn's algorithm.
|
|
* `finiterectlat-scatter.py`: Plane wave scattering.
|
|
* `finiterectlat-constant-driving.py`: Rectangular array response to
|
|
a driving where a subset of particles are excited by basis VSWFs with the
|
|
same phase.
|
|
|
|
### Infinite lattices
|
|
|
|
* `rectlat_simple_modes.py`: Search for lattice modes using Beyn's algorithm.
|
|
* `infiniterectlat-k0realfreqsvd.py`:
|
|
Evaluate the lattice mode problem singular values at the Γ point for a real frequency interval.
|
|
Useful as a starting point in lattice mode search before using Beyn's algorithm.
|
|
* `infiniterectlat-scatter.py`: Plane wave scattering.
|
|
|
|
|
|
General 2D lattices
|
|
-------------------
|
|
|
|
### Infinite lattices
|
|
|
|
These can contain several scatterers per unit cell. Symmetry adapted bases currently not implemented.
|
|
|
|
* `lat2d_modes.py`: Search for lattice modes using Beyn's algorithm.
|
|
* `lat2d_realfreqsvd.py`:
|
|
Evaluate the lattice mode problem singular values at the Γ point for a real frequency interval.
|
|
Useful as a starting point in lattice mode search before using Beyn's algorithm.
