abstract = {In  this  paper,  we  show  a  simulation  strategy  for
composite dispersive thin-panels, starting from their microscopic
characteristics   and   ending   into   a   time-domain   macroscopic
model.  In  a first  part,  we  revisit  different semianalytic  methods
that   may  be  used  to  obtain  the  S-parameter  matrices.   The
validity  of  them  is  assessed  with  numerical  simulations  and
experimental  data.  We  also  include some  formulas  that  may  be
used  to  tailor  the  shielding  effectiveness  of  panels  in  a  design
phase.  In  a  second  part,  we  present  an  extension  to  dispersive
media  of  a  subgridding hybrid  implicit–explicit algorithm  finite
difference  time  domain  (FDTD)  devised  by  the  authors  to  deal
with  that  kind  of  materials.  The  method,  here  presented  and
applied  to  the  FDTD  method,  is  a  robustly  stable  alternative
to  classical  impedance  boundary  condition  techniques. For  this,
a previous analytical procedure allowing to extract an equivalent
effective media from S-parameters is presented, thus making this
road  map  able  to  simulate  any  kind  of  dispersive  thin  layer.
A  numerical  validation  of  the  algorithm  is  finally  shown  by
comparing  with experimental  data.},
