Abstract

We introduce the Geometry Matrix formalism, a modular framework for modeling active plasmonic nanoparticles in the quasi-static and Mie regimes. This approach predicts threshold gain conditions, emission spectra, and modal instabilities in gain-assisted metal nanostructures, offering a unified perspective on plasmonic nano-resonators and improving predictive modeling for plasmonic spasers.
