Metamaterials are artificially engineered devices that go beyond the properties of
conventional materials in nature. Metamaterials allow for the creation of negative refractive …

This paper presents an efficient equivalent circuit approach (ECA), based on a Floquet
modal expansion, for the study of the co-and cross-polarization in frequency selective …

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 …

This paper proposes a compact model for chipless radio frequency identification (RFID) tag.
This compact scalable model consists of capacitors, inductors, and resistors of which their …

This letter shows an efficient hybrid method to study stacks of identical frequency selective
surfaces (FSSs) separated by possibly different dielectrics. The method takes advantage of …

The dielectric layers surrounding a metasurface have a large impact on its frequency and
angular response. The notion of effective permittivity captures this dependence by …

Multilayer metasurfaces have attracted much attention for broad bandwidth and high
transmission efficiency. However, the electromagnetic (EM) coupling will be significant and …

4.5 Conclusions In this chapter, we investigated a series of methods to facilitate the analysis
and design of reconfigurable RF devices based on the use of liquid crystal (LC). First, we …
