Module particles 

Clusters of arbitrary spherical or cylindrical particle T-matrices.

Upstream: treams.TMatrix.cluster(tmats, positions).interaction.solve() and its TMatrixC twin. The gradients are a treams-rs extension.

Structs

ParticleClusterGradient

Gradients of the inputs of particle_cluster and cylindrical_particle_cluster, in the order of their arguments: the local matrices, the positions of the basis and the wavenumbers.

ParticleClusterResidual

What particle_cluster and cylindrical_particle_cluster save for their pullback: the interaction solve, with one local block per particle, and the expansion residual of the coupling.

Functions

couple 🔒

Solve the interaction of the local matrices through the singular expansion coupling. The solve owns the only coupling matrix; the expansion pullback needs just the geometry.

cylindrical_particle_cluster

Couple the cylindrical T-matrices of different particles with fixed axial mode labels and solve for the interacting T-matrix.

framed_state_size 🔒

The two sections have independent fixed layouts. Framing lets each component validate its complete byte count before restoring numerical arrays.

invalid_state 🔒

particle_cluster

Couple the spherical T-matrices of different particles in a common embedding medium and solve for the interacting T-matrix.
