| contents | This work presents an updated version of the previously released freeware MAN (Modal Analysis of Nanoresonators) [Comput Phys Commun 284, 108627 (2023)], a software package designed to efficiently compute and normalize quasinormal modes (QNMs) and to use them for the analysis of the optical response of electromagnetic resonators. The current release introduces three major enhancements. First, Version 9 extends the capabilities of Version 8 by incorporating new models and functions dedicated to systems involving two-dimensional materials, such as graphene. Second, based on a newly developed coupled-QNM theory, a new toolbox has been implemented that enables the computation of the complex coupling coefficients between the modes of coupled resonators using the individual QNMs of the uncoupled cavities. Finally, we introduce new functions that allow for the direct evaluation of Fano parameters for the extinction cross-section directly from the QNM field distribution. |
