Theory

This section presents the theoretical foundation behind the MQED-QD toolkit. We begin with the macroscopic quantum electrodynamics (MQED) framework that underpins all simulations — including the dyadic Green’s function, dipole–dipole interaction, generalized dissipation, and the resonance energy transfer enhancement factor — and then describe the specific geometries for which the Green’s function is evaluated.
