Abstract

Der Polarisationstransformator (PT) enthält 3 bis 8 Polarisationselemente (W1, W2, ...), von denen mindestens 3 individuell angesteuert werden und bei dem die Eigenmoden so eingestellt werden können, daß sich zumindest insgesamt näherungsweise eine Laufzeitdifferenz zwischen den Eigenmoden von π rad ergibt. Durch lineare Änderung der Einstellwerte kann jeder Polarisationszustand erreicht werden.
