New plasmonic cavity resoantors are demonstrated by Junxi Zhang and co-workers in article number 1600731 by using metamaterials consisting of gold nanotube arrays. Hybrid plasmonc cavity modes, resulting from near-field coupling of transverse and longitudinal modes, perform electric fields partially localized into pores and at two ends based on extraordinary optical transmission coupling effect through inner nanochannels of the gold nanotubes.
