dc.description.abstract | In this paper, we explore the excitation of magnetic current surface waves in truncated
periodic arrays of slots in a conducting screen. A specialized Method of Moments (MoM) implementation is
presented, which makes it possible to efficiently solve the scattering problem involving truncated arrays
of several thousands of slots. By making use of the dispersion diagrams of surface waves propagating
along infinite periodic arrays of slots, we are able to explain the absence of magnetic current surface waves
in the arrays at frequencies in the neighborhood of the transmission peak associated to the slots natural
resonances (length roughly equal to half the wavelength), while they are present when the arrays are excited
under extraordinary transmission (EOT) conditions. In order to experimentally check this different behavior,
an aluminium plate periodically perforated with slots has been fabricated and fed by means of a pyramidal
horn, and the electric field behind the plate has been measured with a planar near-field system at a few
centimeters from the plate. Our experimental results and MoM simulations agree, demonstrating the presence
of a standing wave pattern of magnetic current surface waves at the EOT frequency, and the absence of surface
waves at the slots natural resonant frequency. | es |
