“…Also non-uniform current densities were considered 40 – 44 , as well as finite dimensions of the magnetic medium 3 , 39 , 40 , 42 , 45 . Furthermore, the spin-wave radiation impedance has also been derived for forward volume spin waves 3 , 38 , 39 , 44 – 48 as well as backward volume waves 3 , 43 , 44 , 46 , 48 , 49 . Nevertheless, all these approaches require numerical methods to find the impedance and do not allow for simple approximate expressions that can be implemented in electrical models and equivalent circuits.…”

We derive a lumped circuit model for inductive antenna spin-wave transducers in the vicinity of a ferromagnetic medium. The model considers the antenna’s Ohmic resistance, its inductance, as well as the additional inductance due to the excitation of ferromagnetic resonance or spin waves in the ferromagnetic medium. As an example, the additional inductance is discussed for a wire antenna on top of a ferromagnetic waveguide, a structure that is characteristic for many magnonic devices and experiments. The model is used to assess the scaling properties and the energy efficiency of inductive antennas. Issues related to scaling antenna transducers to the nanoscale and possible solutions are also addressed.

“…This systematic design method is then applied, in “ Classes of practical transducers ”, to various transducer classes based on multi-conductor lines, which are not only capable of achieving wide-band transduction but are also suitable for efficient, nanoscale transducers. The radiation impedance of multi-conductor lines has previously been analyzed 28 – 31 , but the full benefits of multi-conductor lines, such as wide-band transduction, higher radiation resistance enabling efficient MNs, and efficient transduction at shorter wavelengths have not been fully considered nor appreciated. Conclusions for various applications and recommendations for future work are presented in “ Conclusion ”.…”

This paper presents a system-level efficiency analysis, a rapid design methodology, and a numerical demonstration of efficient sub-micron, spin-wave transducers in a microwave system. Applications such as Boolean spintronics, analog spin-wave-computing, and magnetic microwave circuits are expected to benefit from this analysis and design approach. These applications have the potential to provide a low-power, magnetic paradigm alternative to modern electronic systems, but they have been stymied by a limited understanding of the microwave, system-level design for spin-wave circuits. This paper proposes an end-to-end microwave/spin-wave system model that permits the use of classical microwave network analysis and matching theory towards analyzing and designing efficient transduction systems. This paper further compares magnetostatic-wave transducer theory to electromagnetic simulations and finds close agreement, indicating that the theory, despite simplifying assumptions, is useful for rapid yet accurate transducer design. It further suggests that the theory, when modified to include the exchange interaction, will also be useful to rapidly and accurately design transducers launching magnons at exchange wavelengths. Comparisons are made between microstrip and co-planar waveguide lines, which are expedient, narrowband, and low-efficiency transducers, and grating and meander lines that are capable of high-efficiency and wideband performance. The paper concludes that efficient microwave-to-spin-wave transducers are possible and presents a meander transducer design on YIG capable of launching $$\varvec{\lambda = 500}\,$$ λ = 500 nm spin waves with an efficiency of − 4.45 dB and a 3 dB-bandwidth of 134 MHz.
