DOI: 10.1007/s10921-021-00815-4
Abstract: Extensional edge waves propagate along the edges of plates, with low attenuation in the propagation direction and amplitude decreasing rapidly (within one or two wavelengths) in the direction perpendicular to the plate edge. This makes… read more here.

DOI: 10.1016/j.jmps.2018.08.017
Abstract: Abstract We propose a new type of platonic crystal, which includes spiral resonators with low-frequency resonant vibrations. The special dynamic effects of the resonators are highlighted by a comparative analysis of dispersion properties of homogeneous… read more here.

Abstract: Abstract In this article, we develop a unified perspective of unidirectional topological edge waves in nonreciprocal media. We focus on the inherent role of photonic spin in nonreciprocal gyroelectric media, i.e. magnetized metals or magnetized… read more here.
