Can anybody help us in our quest to understand the process of modulating
e.m. waves by polarization, more specifically in the way that it was applied
in Carl Sagan's novel, "Contact". What kind of modulatores might have been
used, which frequencies are more practical for this modulation? Mathematical
fundaments based on Stokes parameters and Poincaré spheres - how are they
treated in this picture?

Luisa and Paula
