Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

open access: yesAdvanced Materials, EarlyView.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

Inversion for the Composite Moment Tensor

Bulletin of the Seismological Society of America, 2015
Abstract The composite moment tensor is defined in analogy to the composite focal mechanism as the averaged representative seismic moment tensor characteristic for a focal area under study. In contrast to the composite focal mechanism, which provides information on shear faulting, the composite moment tensor can provide additional information on ...

Moment tensors and micromechanical models

Tectonophysics, 2002
Abstract A numerical modelling approach that simulates cracking and failure in rock and the associated seismicity is presented and a technique is described for quantifying the seismic source mechanisms of the modelled events. The modelling approach represents rock as an assemblage of circular particles bonded together at points of contact.
