Magnetically controllable 1D magnetophotonic crystal in millimetre wavelength band

We analyse the results of experimental and theoretical studies of a 1D magnetophotonic crystal based on the ferrite magnetic periodic multilayered structure. The adequacy of the proposed phenomenological model for description of this crystal in the millimetre waveband is tested experimentally. The possibility to control the spectra of such a structure by variation of the external magnetic field is demonstrated. It is shown that detuning of frequency stop-bands in the spectrum is determined first of all by dispersive properties of the ferrite. The promising applications of such structures as tunable extra high frequency devices are discussed.
