In order to do that, I need to be able to set the electric field at

otherwise?
Well, you can call meep::fields::initialize_field. In Scheme you
could do, for example:
(init-fields)
(meep-fields-initialize-field fields Ez myfunc)
where myfunc(x) is a function of one argument (a vector x) that
returns the desired Ez at that point. Similarly for other field
components.
If this is not quite what you want, you may need to modify the Meep
source code, perhaps starting with the code for initialize_field (in
src/initialize.cpp) to guide you.
