“…11 is very small in the passband and that it strongly depends on the conductivity, i.e., on the losses. It can be readily verified from (13) to (16) that, in the lossless case, the reactance contribution of the zero-order mode is zero within the passband and that its course is governed by the higher-order ones. It is not possible to derive the reactance in this band from the Hilbert transform of the real part 9:.in this range for the following reasons.…”

The excitation of magnetostatic surface waves (MSSW) is formulated in terms of vector instead of scalar potential theory. The method is two‐dimensional and is suitable to handle the MSSW generation in any plane‐parallel film stack by striplines with predefined current distributions. The absorption due to the finite electrical conductivity and the Gilbert precession damping are accounted for. Both the real and imaginary parts of the radiation impedance are explicitly derived for a stack with one ground plane with finite electrical conductivity, located at finite distance from the magnetic film which possesses a Gilbert type of damping. One microstrip line is located between the magnetic film and the ground. Numerical results for these configurations are presented for a variety of parameters, such as stripline geometry, the ground‐plane conductivity, ground‐plane distance, and Gilbert damping constant.

“…В такой конфигурации на входную антенну P in , расположенной на MC1, подавался СВЧ-сигнал с генератора Anritsu MG3692C. В данной геометрии вдоль МК возможным оказывалось возбуждение поверхностной магнитостатической волны (ПМСВ) [19,20]. Прием сигнала осуществлялся выходными антеннами P 1 и P 2 на MC1 и MC2, соответственно.…”

The control regimes of dipole coupling in the lateral system of non-identical magnonic crystals are investigated by the method of Mandelstam-Brillouin spectroscopy and by the method of micromagnetic modeling. The modes of spatial and frequency selection of the spin-wave signal near the frequency of the band gap zone of the magnonic crystal are revealed. The influence of changes in geometric parameters on the properties of waveguide modes near the frequency of the Bragg resonance is investigated. The results obtained can be used to create microwave signal processing devices, such as demultiplexers, power dividers, couplers.

“…Here, the excitation of SW was performed in the wide regular waveguide section. It is known that in the case of the magnons and SWs excitation via application of external microwave field generated by the microstrip line, the power of excited SW depends on the radiation resistance per unit length summed over all width modes and the overlapping length of microstrip and planar finite width waveguide [Bajpai, 1985]. Another reason to fabricate the irregular waveguide with the linear variation of transverse width (e.g., adding the tapered region to magnetic waveguide [Demidov 2009]) is to control the wavenumbers of simultaneously propagating SW width modes [Beginin 2013].…”

An irregular tapered ferrite waveguide with a periodically width-modulated region was investigated. By using space-and time-resolved Brillouin light scattering spectroscopy, we measured the features of the intermodal interaction of width modes and their scattering at the boundaries of the waveguide. Near the band-gap frequency region, the spatial pattern of the spin-waves depends on the mode interaction in the periodically width-modulated yttrium-iron-garnet waveguide. These experimental results are important for controlling spin-wave propagation in width-modulated magnetic structures for future spintronic devices.
