In this work, we numerically investigate the electromagnetic resonances on two-dimensional
tandem grating structures. The base of a tandem grating consists of an opaque Au substrate …

Enhanced optical transmission (EOT), which results from the incident light interacting with
the subwavelength nanostructures patterned in a metallic film, showcases the excitation of …

The phenomenon of extraordinary transmission (EOT) through perforated metal sheets (hole
arrays) has been an interesting field of research since its discovery due to its potential …

Subwavelength nanostructures have exhibited different and controllable optical
characteristics from their original material, leading a way to artificial metamaterials and …

Metal-dielectric-metal fishnet structures in general consist of a single functional layer along
the direction of propagation. They support different kinds of electromagnetic modes and …

Nanoscopically thin metallo-dielectric layers formed by noble metals, such as gold or silver,
and oxides, SiO2, MgO or TiO2 for example, have a range of interesting optical properties …
