Accelerating frequency-domain numerical methods for weakly nonlinear focused ultrasound using nested meshes
Samuel P. Groth, Pierre Gélat, Seyyed R. Haqshenas +4
The numerical simulation of weakly nonlinear ultrasound is important in treatment planning for focused ultrasound (FUS) therapies. However, the large domain sizes and generation of…
Preconditioning the discrete dipole approximation
Samuel P. Groth, Athanasios G. Polimeridis, Jacob K. White
The discrete dipole approximation (DDA) is a popular numerical method for calculating the scattering properties of atmospheric ice crystals. The standard DDA formulation involves t…
Circulant preconditioning in the volume integral equation method for silicon photonics
Samuel P. Groth, Athanasios G. Polimeridis, Alexandra Tambova +1
Recently, the volume integral equation (VIE) approach has been proposed as an efficient simulation tool for silicon photonics applications [J. Lightw. Technol. 36, 3765 (2018)]. Ho…
Adiabatic absorbers in photonics simulations with the volume integral equation method
Alexandra Tambova, Samuel P. Groth, Jacob K. White +1
This paper describes the implementation and performance of adiabatic absorbing layers in an FFT-accelerated volume integral equation (VIE) method for simulating truncated nanophoto…
A hybrid numerical-asymptotic boundary element method for high frequency scattering by penetrable convex polygons
Samuel P. Groth, David P. Hewett, Stephen Langdon
We present a novel hybrid numerical-asymptotic boundary element method for high frequency acoustic and electromagnetic scattering by penetrable (dielectric) convex polygons. Our me…
