This work presents a review of the generalized intersection approach (GIA) for
electromagnetic array antenna beam-shaping synthesis. After briefly describing the …

Electromagnetic metasurfaces are structured surfaces consisting of a thin array of
subwavelength elements with engineered scattering properties, thus providing a promising …

Microwave and millimeter-wave antennas focused in their radiative near-field (NF) region,
which are usually named as near-field focused (NFF) antennas, are becoming increasingly …

We present the design and experimental demonstration of a cavity-backed, holographic
metasurface capable of focusing microwaves in the Fresnel zone. The circular cavity …

A hybrid effective approach is proposed to focus the intensity of a vector field generated by
an arbitrary fixed-geometry array antenna into a target point and keep it bounded elsewhere …

We present the design and experimental demonstration of an efficient holographic
metasurface aperture that focuses microwaves in the Fresnel zone. The proposed circular …

In this work, a procedure based on the Intersection Approach, is proposed to synthesize the
near-field pattern of transmitarray antennas. First, the model for the computation of the …

This paper investigates the focusing features of a multi-panel near-field focused (NFF)
antenna. Differently from conventional NFF planar arrays, the proposed configuration is …

This article presents a double-layer four-corner-fed slotted waveguide sparse array antenna
designed for the near-field-focused applications in the X-band. Generally, it is challenging to …

In this letter, an analytical method based on projected spatial Fourier transform (PS-FT) is
presented to flexibly synthesize the 3-D spatially-shaped microwave fields. Distinct from the …
