Interferometric control of the absorption in optical patch antennas

Abstract Optical patch nano-antennas possess unique absorption, field enhancement and concentration capabilities – but their crosssection, as well as their response outside of normal incidence are not well understood. Here we explain the large cross-section by considering that each patch nanoantenna...
