Data generated internal solutions for the plasma wave equation: error bounds and numerical experiments in two dimensions
Vladimir Druskin, Shari Moskow, Mikhail Zaslavsky
We consider the computation of internal solutions for a time domain plasma wave equation with an unknown potential from boundary response data. The internal solutions are compu…
On optimality and bounds for internal solutions generated from boundary data-driven Gramians
V. Druskin, S. Moskow, M. Zaslavsky
We consider the computation of internal solutions for a time domain plasma wave equation with unknown coefficients from the data obtained by sampling its transfer function at the b…
A Krylov projection algorithm for large symmetric matrices with dense spectra
Vladimir Druskin, Jörn Zimmerling
We consider the approximation of for large s.p.d. with dense spectrum and , . We target the com…
ROM inversion of monostatic data lifted to full MIMO
V. Druskin, S. Moskow, M. Zaslavsky
The Lippmann--Schwinger--Lanczos (LSL) algorithm has recently been shown to provide an efficient tool for imaging and direct inversion of synthetic aperture radar data in multi-sca…
Monotonicity, bounds and extrapolation of Block-Gauss and Gauss-Radau quadrature for computing
Jörn Zimmerling, Vladimir Druskin, Valeria Simoncini
In this paper, we explore quadratures for the evaluation of where is a symmetric positive-definite (s.p.d.) matrix in , is a tall matr…
Regularized Reduced Order Lippman-Schwinger-Lanczos Method for Inverse Scattering Problems in the Frequency Domain
Justin Baker, Elena Cherkaev, Vladimir Druskin +2
Inverse scattering has a broad applicability in quantum mechanics, remote sensing, geophysical, and medical imaging. This paper presents a robust direct reduced order model (ROM) m…
