A level set-based interface-enriched topology optimization for the design of phononic crystals with smooth boundaries

, 2023
Phononic crystals can be designed to show band gaps—ranges of frequencies whose propagation is strongly attenuated in the material. In essence, their working principle is based on destructive interference of waves reflecting from the periodic arrangement

Determination of the Fermi surface and field-induced quasiparticle tunneling around the Dirac nodal loop in ZrSiS

Physical Review Research, 2020
Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semimetals, but only in a relatively few cases has this goal been realized.

A Practical Approach for Extracting Tree Models in Forest Environments Based on Equirectangular Projections of Terrestrial Laser Scans

Remote Sensing, 2013
Extracting 3D tree models based on terrestrial laser scanning (TLS) point clouds is a challenging task as trees are complex objects. Current TLS devices acquire high-density data that allow a detailed reconstruction of the tree topology.
