focus light—have experienced growing research interest in recent years as they can realize …

Metasurfaces have recently risen to prominence in optical research, providing unique
functionalities that can be used for imaging, beam forming, holography, polarimetry, and …

Metasurfaces, artificial 2D structures, have been widely used for the design of various
functionalities in optics. Jones matrix, a 2× 2 matrix with eight parameters, provides the most …

Polarimetry plays an indispensable role in modern optics. Nevertheless, the current
strategies generally suffer from bulky system volume or spatial multiplexing scheme …

Metasurfaces have proved to possess extraordinary properties and propelled the
development of versatile functional devices in the terahertz domain, but the intrinsic …

Optical metasurfaces offer a compact platform for manipulation of the amplitude, phase, and
polarization state of light. Independent control over these properties, however, is hindered …

The new paradigm was introduced for achieving excellent electromagnetic (EM) waves
absorption through multi-layer superimposed quasiperiodic-metamaterials, which were …
