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”.
