The results of theoretical and experimental study of anisotropic propagation of magnetostatic waves (MSW) in ferromagnetic thin-film microsize waveguides are presented. Electrodynamic model of tangentially magnetized ferromagnetic waveguide is developed. On the base of the model, the main features in rotation of group velocity vector of volume MSW (VMSW) by rotating a wave vector and a vector of an external bias magnetic field relative to the axis of symmetry of the waveguide are demonstrated. It is shown, that a decrease in a width of the waveguide to the micron size leads to non-reciprocal propagation of VMSW and to increase of angular divergence between the phase and group velocities of VMSW. The experimental research of T-shaped ferromagnetic microwaveguide demonstrates the difference in power levels of a signal that is branched in the shoulders of T-shaped waveguide when the bias magnetic field is rotated in the waveguide plane.

AbstractA novel magnetooptic (MO) Bragg cell modulator that utilizes a magnetostatic forward volume wave (MSFVW) oscillator is presented. The carrier frequency of the MSFVW signals involved in the MO interaction is tuned linearly from 2.112 to 3.274 GHz by increasing an external bias magnetic field from 2350 to 2900 Oe. Compared with a conventional magnetostatic wave (MSW) delay line-based MO Bragg cell modulator, the proposed modulator can provide significantly higher diffraction efficiency owing to reduction of insertion losses in the MSFVW oscillator. Furthermore, the oscillator-type MO modulator can be more easily integrated with other MMIC devices.

Velocity Of Propagation

AbstractIt has been shown that uncoupled surface waves of SH type can be propagated without any dispersion in an electrically conducting semi-infinite elastic medium provided a uniform magnetic field acts non-aligned to the direction of wave propagation. In general, the velocity of propagation will be slightly greater than that of plane shear waves in the medium.

Starting from the two-fluid model hydrodynamic equations, a dispersion relation is obtained for wave propagation through a two-temperature plasma perpendicular to the direction of the spatially uniform external magnetic field B0cosω0t and several excitation conditions are deduced.
