dc.description.abstract | Many frequency-selective surface (FSS) structures
are based on the use of a single periodic array of slot/apertures in
a conducting sheet embedded in a layered medium. However, it is
well known that stacking several conducting sheets and breaking
the alignment of the stack can bring multiple benefits to the
structure. In this article, the analysis and design of stacks of 2-D
aperture arrays are carried out by exploiting as much as possible
all the potential of a rigorous and systematic formulation based
on the multimodal equivalent circuit approach (ECA). A key fea ture of the formulation is that linear transformations between the
apertures of adjacent plates (rotation, translation, and scaling)
can be dealt with from a purely analytical perspective. This fact
is of potential interest for many practical applications, such as
the design of polarization converters, absorbers, filters, and thin
matching layers. When the apertures have an arbitrary geometry,
it can be applied a hybrid approach that combines the ability
of commercial simulators to handle arbitrary geometries with
the fast computation times and physical insight of the ECA.
In general, either the purely analytical or the hybrid approach
can be applied in those many practical scenarios where the
spatial profile of the electric field on the considered apertures
hardly changes with frequency. As an additional feature of the
approach, the dispersion properties (phase/attenuation constants
and Bloch impedance) of infinite periodic stacks can be derived,
and in particular, analytical expressions for the mirror- and
glide-symmetric configurations are provided. | es |
