UltraRay: Introducing Full-Path Ray Tracing in Physics-Based Ultrasound Simulation [PDF]

Traditional ultrasound simulators solve the wave equation to model pressure distribution fields, achieving high accuracy but requiring significant computational time and resources. To address this, ray tracing approaches have been introduced, modeling wave propagation as rays interacting with boundaries and scatterers. However, existing models simplify

Spectral broadening from turbulence in multiscale lower hybrid current drive simulations

Nuclear Fusion, 2022
The scattering of lower hybrid (LH) waves due to scrape-off layer filaments is investigated. It is revealed that scattering can account for the LH spectral gap without any ad hoc modification to the wave-spectrum.

Simulation as a Tool for Understanding Experimental Observations—Ion Beam Extraction from an ECRIS

Plasma, 2022
A model for the simulation of ion beam extraction from an electron-cyclotron resonance ion source is proposed. It is based on the simple fact that charged particles follow magnetic field lines. Therefore, magnetic field lines are used to generate initial
