Abstract

Our main goal is to describe the basic steps for the emission control of the electromagnetic field leaving a tailored slit on a gold film, combined with a plasmonic grating designed on the output face, in order to make the emitted beam acquire the desired irradiation diagram (ID). A suitable numerical tool developed for a fast evaluation of the slit-grating system’s ID allows to spare time in the definition of the selected configurations. The customization of the ID is a primary step for the design of more complex structures with potential useful capabilities for the manipulation of impinging light waves and the consequent rise of interesting electromagnetic patterns.
