Numerical discretization of the large-scale Maxwell's equations leads to an
ill-conditioned linear system that is challenging to solve. The key requirement
for successive solutions of this linear system is to choose an efficient
solver. In this work we use Perfectly Matched Layers (PML) to increase this
efficiency. PML have been widely used to truncate numerical simulations of wave
equations due to improving the accuracy of the solution instead of using
absorbing boundary conditions (ABCs). Here, we will develop an efficient solver
by providing an alternative use of PML as transmission conditions at the
interfaces between subdomains in our domain decomposition method. We solve
Maxwell's equations and assess the convergence rate of our solutions compared
to the situation where absorbing boundary conditions are chosen as transmission
conditions
