Electromagnetic metastructures stand for the artificial structures with a characteristic size
smaller than the wavelength, which may efficiently manipulate the states of light. However …

Metamaterials (MTMs) are artificial structures characterized by flexible and designable
electromagnetic (EM) properties, including permittivity, permeability, and refractive index …

A new 2-D ultra-thin transmissive phase gradient metasurface (TPGM) with polarization-
independent property is proposed based on the generalized Snell's law of refraction. The …

Transformation optics asks, using Maxwell's equations, what kind of electromagnetic
medium recreates some smooth deformation of space? The guiding principle is Einstein's …

The transformation optics (TO) technique has been widely applied in the volume reduction of
Luneburg lens (LL) in both optical and microwave regimes. However, it is found that the …

Polarization conversion has been widely explored in the study of metasurfaces in order to
achieve broad operation bandwidths, but its application is still restricted to a few practical …

A transmitarray antenna with an elliptical cylindrical shape is presented for a wide-angle
multibeam radiation in this communication. The transmitarray has a cylindrical radiating …

Modern communication systems will require antennas with adaptive functionality that are
able to modify their performance based on the requirements of the channel. For example …

In this paper, a systematic method to design a quasi-optimum lens profile based on quasi-
conformal transformation optics technique for a given excitation is presented. This method is …

A task-oriented multiscale material synthesis problem is addressed through an instance of
the system-by-design (SbD) paradigm. More specifically, wide-angle impedance matching …
