2021 Fifteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials).
We present a square-lattice photonic crystal that supports chiral topological photonic surface states at the interface to free space. Such unidirectional, back-scattering-immune surface states, as opposed to topological states at the interface betwee

2020 Fourteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials).
We perform theoretical and experimental investigations of the association between surface states of finite, corrugated dielectric photonic crystal and dark modes of dielectric metasurfaces consisting of an isolated single layer of dielectric scattere

Artificially created surfaces or metasurfaces, composed of appropriately shaped subwavelength structures, namely, meta-atoms, control light at subwavelength scales. Historically, metasurfaces have used radiating metallic resonators as subwavelength i

2017 11th International Congress on Engineered Materials Platforms for Novel Wave Phenomena (Metamaterials).
We demonstrate matched toroidal and magnetic dipole resonances in dielectric rod metasurfaces by combining an elliptical rod cross-section or a coupled-rod molecule with inter-cell coupling. Importantly, the resonances remain matched when varying the

Using periodic materials composed of split-ring resonators (SRRs) and continuous wires is, up to now, the most common way of obtaining left-handed behaviour in the microwaves regime. In this work, using transmission simulations and measurements, we e

The disorder driven quantum Hall to insulator transition is investigated for a two-dimensional lattice model. The Hall conductivity and the localization length are calculated numerically near the transition. For uncorrelated and weakly correlated dis

Metamaterials allow for the creation of electromagnetic media with properties that are not found in or, are much weaker in, natural materials. The authors discuss design methods to minimize dissipative loss and the use of gain to compensate dissipati

The authors discuss the design and modeling of electromagnetically induced transparency (EIT) metamaterials and some work on its applications for sensing and for media with nonlinear response. The simplest model to describe classical EIT systems is a

We demonstrate an ultrafast reversible modulation of resonant terahertz (THz) response in strongly photoexcited metamaterials. The transient spectral-temporal response of the dipole transition ~1.6 THz exhibits a distinct non-monotonic variation as a
