Theoretical Demonstration of Weyl Points in 3D srs Photonic Crystals

Not Accessible

Your library or personal account may give you access

Abstract

We present the theoretical study of achiral 2-srs-networks and we show that these structures possess the frequency-isolated linear point degeneracies in their three-dimensional dispersion relations that define the illusive Weyl points. Our results are based on band structure calculations and can be realisable experimentally from microwave to optical frequencies via laser fabrication methods.
