The introduction of electromagnetic (EM) media with unique field manipulation properties,
collectively labelled as metamaterials, has boosted the interest toward the design, the …

In this review paper I discuss electrically thin composite layers, designed to perform desired
operations on applied electromagnetic fields. Starting from a historical overview and based …

This paper presents design and analysis methods for planar antennas based on modulated
metasurfaces (MTSs). These antennas operate on an interaction between a cylindrical …

This paper presents a new theory for analyzing the leaky-wave (LW) mechanism supported
by planar metasurfaces (MTSs) described by continuous, anisotropic, nonuniform, locally …

This article presents the exact closed-form solution for a new planar lens, hereinafter
referred to as reflecting Luneburg lens (RLL). The proposed structure consists of two stacked …

Metasurfaces are thin metamaterial layers characterized by unusual dispersion properties of
surface/guided wave and/or reflection properties of otherwise incident plane waves. At the …

This paper presents an effective approach for the derivation of the two-dimensional (2-D)
frequency-wavenumber dispersion surface of anisotropic metasurfaces (MTSs) consisting of …

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

Metasurfaces (MTSs) have emerged in the last years as a promising platform for next
generation planar devices in a broad range of frequencies, thanks to their unique field …

Metasurfaces (MTSs) constitute a class of thin metamaterials used for controlling plane
waves and surface waves (SWs). At microwave frequencies, they are constituted by a …
