MOUNTAINOUS CULTURAL CROSSROADS: VOYAGES FOR OCHRE QUARRYING

Mountainous cultural crossroads: voyages for ochre quarrying

Recent decades have presented increased interest in provenance studies.However, such research in the sphere of mineral pigments are rare in archaeological dispute.The main aim of this paper is to portray the state of knowledge on that issue, followed by a presentation of ochre outcrops in the Carpathian Basin.The discussion is additionally illustra

Ultrasensitive terahertz sensing with high-Q toroidal dipole resonance governed by bound states in the continuum in all-dielectric metasurface

Toroidal dipole (TD) with weak coupling to the electromagnetic fields offers tremendous potential for advanced design of photonic devices.However, the excitation of high quality (Q) factor TD resonances in these devices is challenging.Here, we investigate ultrahigh-Q factor TD resonances at terahertz frequencies arising from a distortion of symmetr
