Holography has numerous applications because of its capability of arbitrary wavefront
modulation. Computer-generated holograms (CGHs) take it a big step forward. Conventional …

Flat optics, metasurfaces, metalenses, and related materials promise novel on-demand light
modulation within ultrathin layers at wavelength scale, enabling a plethora of next …

Metamaterials can possess extraordinary properties not readily available in nature. While
most of the early metamaterials had narrow frequency bandwidth of operation, many recent …

Multicolor holography can faithfully record the color, depth, parallax, and other properties of
scenes and have thus found numerous applications, for example, in optical document …

In this work, a simple dielectric metasurface hologram is proposed and designed by
combining the electromagnetic vector analysis method and the immune algorithm, which …

Perfect absorbers are highly desirable in many military applications, such as radar cross
section (RCS) reduction, cloaking devices, and also sensor detectors; however, most …

Metasurfaces are extensively studied for the flexible manipulation of wavefront and
polarization of electromagnetic waves with significant merits such as ultra‐thin profiles and …

In this paper, two kinds of dual-band metamaterial absorbers (MMAs) with stable absorption
performance based on fractal structures are proposed. As the key feature, with the increase …

Achieving asymmetric transmission effects, especially in an ultra-broadband frequency
region, is of particular importance in communication systems. Currently available …

The influences of metasurfaces on the propagation of electromagnetic waves generate
several important effects, such as asymmetric transmission and polarization conversion, that …
