An Explicit Mapped Tent Pitching Scheme for Maxwell Equations
Jay Gopalakrishnan, Matthias Hochsteger, Joachim Schöberl +1
We present a new numerical method for solving time dependent Maxwell equations, which is also suitable for general linear hyperbolic equations. It is based on an unstructured parti…
Simulation of Optical Fiber Amplifier Gain Using Equivalent Short Fibers
Dow Drake, Jay Gopalakrishnan, Tathagata Goswami +1
Electromagnetic wave propagation in optical fiber amplifiers obeys Maxwell equations. Using coupled mode theory, the full Maxwell system within an optical fiber amplifier is reduce…
A mass conserving mixed stress formulation for Stokes flow with weakly imposed stress symmetry
Jay Gopalakrishnan, Philip L. Lederer, Joachim Schöberl
We introduce a new discretization of a mixed formulation of the incompressible Stokes equations that includes symmetric viscous stresses. The method is built upon a mass conserving…
Analysis of FEAST spectral approximations using the DPG discretization
Jay Gopalakrishnan, Luka Grubišić, Jeffrey Ovall +1
A filtered subspace iteration for computing a cluster of eigenvalues and its accompanying eigenspace, known as "FEAST", has gained considerable attention in recent years. This work…
