| Annotation | Bandpass transmission line on the basis of uniaxial single-crystal hexaferrites in multidomain area has been proposed in this paper. This line can be used for experimental investigation of excitation and propagation of magnetostatic waves within millimeter wave range in uniaxial single-crystal hexaferrites as well as for designing of bandpass filters and delay lines. Based on it model of tunable bandpass filter with platelet of single-crystal barium hexaferrite in multidomain area with domain structure of some definite type has been designed for the first time. The work presents results of experimental investigations into conditions of excitation and propagation of magnetostatic waves in single-crystal platelet of barium hexaferrite which is the main functional element of the proposed bandpass filter. It has been found out that power attenuation of magnetostatic waves during their propagation is the key factor of signal transmission in the investigated model. It is shown that there is a correlation between intensity, bandwidth of magnetostatic resonances and efficiency of magnetostatic waves transmission in the multidomain area. |
