Summary Data and source code relate to the article Enhanced Purcell factor for nanoantennas supporting interfering resonances [1], whose subject are the effects of coupled resonances and quasibound states in the continuum on the Purcell factor in dielectric resonant nanoantennas. The provided scriptsreproducethe analysis of interfering resonances in a nanodisk coupled to an enclosed emitter and can be easily adapted for further investigations. Structure The cases refer to different aspect ratios of the nanodisk with (a and b) and without (c and d) substrate. The scans reproduce the data used to find the aspect ratios (a and c) supporting the maximal Purcell enhancement. RPExpand [2] is used for Riesz projection expansions, which quantify the interactions of the resonances. The directories resonance and scatteringcontain input files for the commercial software JCMsuite, which rigorously solves Maxwells equations with the finite-element method (FEM). In orderto switch to a custom setup, you must adapt these input files. If you want to recalculate all results, make sure that you remove the directories containing resultbags. These are stored in the directory results, e.g., results/case_a/resultbags. Requirements JCMsuite (tested with version: 4.6.3) Matlab (tested with version: R2019b) In order to run the scripts you must replace the corresponding place holders in the files bya path to your installation of JCMsuite.
