Abstract
A device for converting the propagation mode of radiated energy, ulitizing the Cotton-Mouton effect. It is constituted by a substrate upon which there is deposited an epitaxially produced film of yttrium-iron garnet, magnetized in a direction having at least one component normal to the direction of energy propagation, and with a thickness such that the propagation velocities of the two modes, initial and final, are identical to one another.
