RTR factorisation

05 December, 2023

Objective

This example compares the two ways to calculate VTACS. We compare the far-field spectra for a linear chain of gold spheres, with and without the DisableRTR keyword.

This simulation uses the following input file

ModeAndScheme 2 3
Verbosity 3
MultipoleCutoff 8
Wavelength 300 700 100
Medium 1.7689 # epsilon of water
OutputFormat HDF5 {file}

(with and without the keyword).

Orientation-averaged results

The far-field cross-sections are the same, and timing comparison doesn’t reveal a meaningful difference on this example.
