Circuit analysis of frequency selective surfaces is reviewed with the aim to underline range
of validity of different models and their advantages in terms of simplicity and physical insight …

The spectacular advancements in antenna technologies for control, guidance, surveillance,
and communication applications for airborne platforms have resulted in the realization of …

The transmission and reflection properties of frequency-selective surfaces (FSSs) are
evaluated through a simple and accurate first-order circuit approach. The approximate …

The effects of mutual coupling impact the performance of phased arrays as the beam is
scanned off broadside. Wide-angle impedance matching (WAIM) alleviates this problem …

Glide-symmetric structures have recently emerged as a smart choice to design planar lenses
and electromagnetic bandgap materials. We discuss here the conditions under which a …

A fully analytical multimodal equivalent circuit is presented for the modeling of the scattering
of an obliquely incident plane wave by a two-dimensional (2-D) periodic array of metallic …

A critical discussion on the computation of the dispersion diagram of electromagnetic
guiding/radiating structures with one-dimensional periodicity using general-purpose …

In this paper, we present analytical models to describe artificial dielectric layers (ADLs),
when a lateral shift between layers is present. The alternate lateral displacement between …

In the study of electromagnetic wave propagation and scattering, researchers have always
faced the dichotomy of dealing directly with Maxwell's equations (and their complicated …

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 …
