Abstract: HighlightsWe give closed form expressions of the dispersion relations of surface modes induced by a piezoelectric‐metallic superlattice with a cap layer.We demonstrate a rule about the existence of surface modes in piezoelectric‐metallic superlattice.We show the…

Abstract: We demonstrate nonreciprocal far-field thermal emission and nonreciprocal near-field radiative heat transfer of Weyl semimetal nanoparticles when the circular thermal emission of the particles directionally couples with the spin of the surface modes supported by…

Abstract: We design, simulate, and experimentally characterize an acoustic metasurface comprising of a 1D array of open, sound-hard, cavities, modulated with beyond-nearest-neighbor (BNN) couplings in the form of additional connecting cavities embedded beneath the surface. The…

DOI: 10.1109/jsen.2019.2907508
Abstract: In this paper, an optical sensor design is proposed with low-symmetric photonic crystals that support surface modes. In order to obtain low symmetry, rotational symmetry is broken within the unit cell size while translational symmetry…

DOI: 10.3390/nano10112205
Abstract: In this paper, we provide a theoretical and numerical study of the acoustic properties of infinite and semi-infinite superlattices made out of graphene-semiconductor bilayers. In addition to the band structure, we emphasize the existence and…
