Abstract
A system for modulating a terahertz beam includes a multiferroic nanoparticle heterostructure through which a terahertz beam can be propagated, and means for applying an external direct current (DC) magnetic field to the multiferroic nanoparticle heterostructure and the terahertz beam propagating through it, wherein application of the DC magnetic field modulates one or both of an amplitude and a phase of the terahertz beam.
