On the generation of surface waves in frequency selective structures
Författare
Summary, in English
In this paper, we discuss and analyze the criteria for the existence and the
generation of surface modes in dielectric slabs with and without metallic layers
(frequency selective structures, FSS). The material parameter of the slab is in
general bianisotropic, but the examples and the numerical computations show
only isotropic materials. It is shown that there are three different categories
of resonances occurring in power transmission and power reflection in a FSS,
i.e., 1) resonances in the array, 2) surface wave excitations, and 3) onset of
grating lobes.
