The cover picture of the current issue shows the local enhancement of the electric field magnitude in a gap plasmon–polariton resonator. This configuration consists of three silver strips of 20 nm thickness and 65 nm, 65 nm, and 130 nm width, respectively, all being illuminated by a p‐polarized plane wave with wavelength of ∼615 nm. The enhancement is particularly strong (∼26) in a 5 nm air gap between two strips. The picture relates to the Feature Article by T. Søndergaard and S. I. Bozhevolnyi (pp. 9–19) on optical resonators based on nm‐thin submicron‐wide metal strips in which resonances and strong near fields in narrow air‐gaps are obtained by utilizing plasmonic waves and the electric field boundary conditions. Thomas Søndergaard is presently working as a post‐doc at the Department of Physics and Nanotechnology, Aalborg University, Denmark, on the project “Plasmonic nanostructures for biomolecular spectroscopy and microscopy”.
