We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

In the past few years, great effort has been devoted to the fabrication of highly efficient,
broadband radome and stealth (R&S) structures for distinct control, guidance, surveillance …

A unified spectral and temporal representation is introduced for nondiffracting waves. We
consider a set of elementary broadband X waves that spans the commonly considered …

A very small focal-to-diameter (F/D) ratio transmitarray for compact antenna test range
(CATR) application is proposed in this article. The transmitarray comprises a feed antenna, a …

A systematic approach is presented to exploit the rich field transformation capabilities of
Electromagnetic (EM) metasurfaces for creating a variety of illusions using the concept of …

A high numerical aperture (NA= 0.92) square all-silicon metalens is designed for a
wavelength of λ= 0.11883 mm with a focal length of 16.8λ and a side length of 104.4λ …

Development work of a 119 GHz compact antenna test range (CATR), based on a 2.4 m/spl
times/2.0 m hologram and its application on the Odin telescope tests are described. The …

The advancement of lithography, mass spectrometry and other technologies is increasingly
requiring the high-quality focusing of extreme ultraviolet (EUV) beams. Traditional …

Abruptly autofocusing terahertz (THz) ring-Airy beam has been generated by transmissive
plasmonic metasurface at a single frequency in the earlier work. However, the transmission …

We synthesize amplitude-and phase-type computer-generated holograms (diffractive
gratings) for shaping millimeter-wave fields. We design holograms using quasi-optical back …
