Introduction

This projects aims at developing a fast Maxwell's Equation solver using using the discontinuous Galerkin method. As first steps to develop this solver, we are developing a library which allows us to solve the 1D wave equation and the 2D wave equation using discontinuous Galerkin method.

1D Wave equation

The 1D wave equation solver is aimed at finding the time evolution of the 1D wave equation using the discontinuous Galerkin method. The 1D wave equation is given by the equation:

1d_wave_eqn

where,

u

F

where, c is a number which denotes the wave speed.

2D Wave Equation Solver

The 2D wave equation solver is aimed at finding the time evolution of the 2D wave equation using the discontinuous Galerkin method. The 2D wave equation is given by the equation:

2d_wave_eqn

where,

u

F

c

where, c_0 and c_1 denotes the component of the wave speed in the hat_i and hat_j direction respectively.

Through the development of the 2D wave equation solver, the code and the algorithms developed here will help in creating the 2D Maxwell's equation solver. Currently the 2D wave equation solver will focus on solving the wave equation in a rectangular domain in the xy plane, with periodic boundary conditions.
