Two Frameworks and their Fourth Order Implicit Schemes for Time Discretization of Maxwell's Equations
Archana Arya, Kaushik Kalyanaraman
Our work is about energy conserving fourth-order time discretizations of a three-field formulation of Maxwell's equations in conjunction with a spatial discretization using higher-…
An Arbitrarily Higher-Order Time Implicit Scheme for Maxwell's Equations
Archana Arya, Kaushik Kalyanaraman
We propose an arbitrarily higher (even) order implicit leapfrog scheme for time discretization of a three-field formulation of Maxwell's equations. We use this in conjunction with…
Quantifying macrostructures in viscoelastic sub-diffusive flows
Tanisha Chauhan, Kaushik Kalyanaraman, Sarthok Sircar
We present a theory to quantify the formation of spatiotemporal macrostructures (or the non-homogeneous regions of high viscosity at moderate to high fluid inertia) for viscoelasti…
Energy Conserving Higher Order Mixed Finite Element Discretizations of Maxwell's Equations
Archana Arya, Kaushik Kalyanaraman
We study a system of Maxwell's equations that describes the time evolution of electromagnetic fields with an additional electric scalar variable to make the system amenable to a mi…
