I have to program explicit and implicit scheme. Then apply perfect matched layer boundary condition on them. And finally extended to a wide bandwidth formulation (WD TD-BPM) using Padé approximants.
and I have done the explict scheme but the problem is that its not giving me the right values.
the only thing I need help in is to make explicitt method working and do explicit method. And I have the equations for implementing Perfectly matched layer and making Wideband scheme.
