Effective Wavelength Scaling for Optical Antennas
Abstract
In antenna theory, antenna parameters are directly related to the wavelength $\ensuremath{\lambda}$ of incident radiation, but this scaling fails at optical frequencies where metals behave as strongly coupled plasmas. In this Letter we show that antenna designs can be transferred to the optical frequency regime by replacing $\ensuremath{\lambda}$ by a linearly scaled effective wavelength ${\ensuremath{\lambda}}_{\mathrm{eff}}={n}_{1}+{n}_{2}\ensuremath{\lambda}/{\ensuremath{\lambda}}_{p}$, with ${\ensuremath{\lambda}}_{p}$ being the plasma wavelength and ${n}_{1}$, ${n}_{2}$ being coefficients that depend on geometry and material properties. It is assumed that the antenna is made of linear segments with radii $R\ensuremath{\ll}\ensuremath{\lambda}$. Optical antennas hold great promise for increasing the efficiency of photovoltaics, light-emitting devices, and optical sensors.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
