Using Diffraction Anomalies to Produce Strong Enhancement of Magnet-Optic Behaviour

Abstract

Diffraction anomalies arising as a consequence of surface structure are shown to be capable of producing enhancement in magneto-optic effects. The magneto-optic behaviour of structured magnetic surfaces is studied in the presence of two anomalies :- (a) where orders pass-off grating horizons and (b) where surface plasmon resonances occur.
