| Summary: | We compute generalized absorption and extinction cross-sections of an optical dipole nanoantenna
in a structured environment. The expressions explicitly show the influence of radiation reaction and
the local density of states on the intrinsic absorption properties of the antenna. Engineering the
environment could allow to modify the overall absorption as well as the frequency and the linewidth
of a resonant antenna. Conversely, a dipole antenna can be used to probe the photonic environment,
in a similar way as a quantum emitter. |
