Metamaterials are materials typically engineered with novel or artificial structures to produce
electromagnetic properties that are unusual or difficult to obtain in nature. Because of their …

Graphene, as a 2D material, has attracted significant attention due to its particular electronic
band structure and unique physical properties. Metasurfaces integrated with graphene hold …

Metamaterials are understood to be artificially engineered materials that exhibit unusual or
difficult to obtain electromagnetic (EM) properties. Such properties would include negative or …

Since 2004, my group at Southeast University has been carrying out research into
microwave metamaterials, which are classified into three catagories: metamaterials based …

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

Antenna requirements for software defined radio (SDR) and cognitive radio (CR) systems
are reviewed and the resulting challenges are discussed. Both concepts imply capabilities …

A novel waveguide slot filtering antenna with an embedded metamaterial is presented. This
filtering antenna consists of a common waveguide slot antenna with longitudinal slots cut on …

A flexible broadband linear polarization converter is proposed based on the metasurface
operating at microwave band. To achieve bandwidth extension property, long and short …

Metasurfaces play an important role in holographic imaging to flexibly manipulate and
control electromagnetic wave fronts. However, metasurface‐based holograms present …

A microstrip-fed truncated monopole antenna with radiation pattern and polarization
reconfigurability is presented. The antenna fabricated on a substrate of dielectric constant …
