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

An effective synthesis procedure for planar antennas realized with nonuniform metasurfaces
(MTSs) excited by a point source is presented. This synthesis potentiates previous …

We explore various possibilities for designing multibeam antennas using a single
metasurface (MTS) aperture. Both single-source and multisource feeding schemes are …

Different types of efficiencies are introduced for metasurface (MTS) antennas based on
single point-source excitation: 1) the feed efficiency ε feed is the power delivered by the feed …

We present analytical expressions for the frequency bandwidth of gain of broadside-beam
metasurface (MTS) antennas. These antennas are based on a transformation between a …

This chapter reports design and analysis methods for planar antennas based on modulated
metasurfaces (MTSs). These antennas transform a surface wave (SW) into a leaky wave by …

The book presents an engineering approach for the development of metamaterials and
metasurfaces with emphasis on application in antennas. It offers an in-depth study …

Metasurfaces (MTSs), the 2D equivalent of metamaterials, are thin artificial layers
characterized by unusual reflection and transmission properties of plane waves and/or …

An assembly comprising a device and an obstacle subjected to an incident electromagnetic
wave of wavelength λ. The obstacle is formed from an electrically conductive material and …

A guided-wave-driven metasurface antenna includes an input for receiving a guided wave;
an output for outputting a free-space wave; and a spatial frequency mixer connected …
