Topological complex transient electromagnetic fields give access to nontrivial light-matter
interactions and provide additional degrees of freedom for information transfer. An important …

Toroidal excitation manifests as currents flowing on the surface of a torus along its meridians
that are known as poloidal currents. Several intriguing phenomena such as nonradiating …

In this work, a novel all-dielectric metasurface made of arrayed circular slots etched in a
silicon layer is proposed and theoretically investigated. The structure is designed to support …

We present two types of refractive index sensors by using tunable terahertz (THz)
metamaterial (TTM) based on two concentric split-ring resonators (SRRs) with different …

In this paper, an all-dielectric metasurface that measures refractive index and temperature
using silicon disks is presented. It can simultaneously produce three resonances excited by …

Arming metasurface with active materials furnishes a feasible solution to dynamically control
