Hi, thanks to Shavkat and Martin, I made it work! The minimum code
snippet is as such:
class MyConductivity(meep.Callback):
def __init__(self):
meep.Callback.__init__(self)
def double_vec(self, r):
return 1e4
mc = MyConductivity()
meep.set_COND_Callback(mc.__disown__())
s.set_conductivity(meep.E_stuff, meep.COND)
Several problems needed to be fixed, e. g. I wanted to __disown__ a
class instance twice for EPS and COND; then I did not know which
component to choose.
I will proceed to implement a precise frequency-domain simulation for
dispersive media and put it on the web for others.
