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

The transmittance of simple one-dimensional gratings and two-dimensional pillar arrays is
usually broadband with poor selectivity in the infrared region. In this paper, it is …

Optical transmission properties of periodic X-shaped plasmonic nanohole arrays in a silver
film are investigated by performing the finite element method. Obvious peaks appear in the …

Homogenization theory is used to derive the effective properties of gratings with complex
subwavelength structures. Going beyond the effect of the filling fraction, geometrical effects …

This paper presents a nanometer-sized metallic film periodically pierced by narrow slits with
ellipse walls deposited on a substrate that demonstrates special optical properties of …

An analytical circuit model is obtained to study the reflection of TM polarized electromagnetic
waves that impinge obliquely on a 1-D periodic corrugated surface consisting of dielectric …

An infrared polarizer consisting of metal-insulator-metal (MIM) gratings is designed with
transmittance exceeding 85% and polarization extinction ratio (ER) higher than 70 dB in the …

In order to benefit from thin-film solar cells cost advantage, increasingly effort is deployed to
maximize their harvesting capability. In this work, we focus on improving an a-Si solar thin …

In this work, we demonstrate both theoretically and experimentally that nonperiodic metallic
gratings can become transparent for broadband terahertz waves. It is shown that broadband …

This paper has investigated the transmission characteristics of inverse polarizing gratings
with tapered slits in the deep ultraviolet band. It is demonstrated that the extraordinary …
