Module spheres 

Dense clusters of homogeneous nonmagnetic spheres in vacuum, with gradients of the radii, permittivities and positions.

Upstream: treams.TMatrix.cluster of TMatrix.sphere T-matrices, then interaction.solve(). The gradients and the reusable factor of sphere_cluster_factor are treams-rs extensions.

Structs

ClusterParts 🔒

SphereClusterGradient

Gradients of the inputs of sphere_cluster, in the order of its arguments.

SphereClusterResidual

What sphere_cluster saves for its pullback: the Mie residual of each sphere, the translation plan between two spheres, the positions and the interaction solve.

Functions

cluster_parts 🔒

coupling_matrix 🔒

Assemble complete particle columns in parallel, for either coupling values or their directional derivative. Self-couplings are exactly zero in both cases.

invalid_state 🔒

sphere_cluster

Solve a finite cluster of homogeneous, nonmagnetic spheres in vacuum.

sphere_cluster_factor

Assemble and factor a sphere cluster for repeated requested illuminations.

vacuum_sphere 🔒

The media of a homogeneous nonmagnetic sphere in vacuum.

validate_spheres 🔒

Check a cluster of homogeneous spheres in vacuum: a positive finite vacuum wavenumber and radii, one finite permittivity and position per sphere, and no two spheres touching or overlapping.
