The electrodynamic modeling of linear arrays of noble metal nanoantennas reveals that plasmonic Bragg modes allow for long-range and large-area emission enhancement. Significant light extraction is possible at large antenna emitter separation (micrometer range) and unfavorable emitter dipole moment orientation. One order of magnitude average emission enhancement for randomly oriented emitters is possible over areas approximate to 20 times larger than a single nanoantenna geometrical cross section

Abstract
The electrodynamic modeling of linear arrays of noble metal nanoantennas reveals that plasmonic Bragg modes allow for long-range and large-area emission enhancement. Significant light extraction is possible at large antenna emitter separation (micrometer range) and unfavorable emitter dipole moment orientation. One order of magnitude average emission enhancement for randomly oriented emitters is possible over areas approximate to 20 times larger than a single nanoantenna geometrical cross section
