We propose a wideband linear polarization converter in transmission mode by bilayer
metamaterial. The polarization converter operates from 0.55 to 1.37 THz with polarization …

Properties of reflection and transmission spectral filters based on Bragg gratings in
subwavelength grating (SWG) metamaterial waveguides on silicon-on-insulator platform …

Subwavelength grating (SWG) waveguides are integrated photonic structures with a pitch
substantially smaller than wavelength for which they are designed, so that diffraction effects …

Subwavelength grating metamaterial racetrack ring resonator (SGMRTR) increases the
coupling strength between the bus waveguide and the ring resonator and thus better …

The concept of encoding metasurfaces makes a connection between the physical
metamaterial particles and the digital code so the digital coding can be performed on the …

We propose, design, fabricate and characterize a subwavelength grating slot (SWGS)
waveguide on silicon platform at short-wave infrared (SWIR) wavelength of 2 μm. The mode …

A Te-free binary phase change material SbBi is proposed as a new inorganic photoresist for
heat-mode lithography. It shows good film-forming ability (surface roughness< 1 nm), low …

Multiband high index of refraction can be realized by thin ring-type terahertz metamaterials
composed of multilayer coupled unit cells. We have focused on the numerical investigation …

A gradient-index Reuleaux-triangle-shaped hole array was fabricated on germanium (Ge)
by nanoimprint lithography and inductively coupled plasma processing as a broadband mid …

Mie-type magnetic and electric resonances in an all-dielectric one-dimensional grating are
theoretically demonstrated in terahertz region. It is found that strong polarization-sensitivity …
