“…One of the main problems in the design of microstrip-excited MSSW transducers is the characterization of the radiation efficiency, i.e., the calculation of the input or radiation impedance. This problem has been solved in the past by calculating the average power carried away by the MSSW excited by the microstrip through the Poynting vector associated with the MSSW [3]- [5], [8]. The calculation of the Poynting vector requires the computation of the MSSW fields.…”

This paper presents a new method for the complete characterization of the radiation of magnetostatic-surface waves in microstrip transmission lines with longitudinal magnetization. This method is based on the analysis of the excitation of leaky modes in microstrip lines and provides both the propagation constant and the complex impedance of the microstrip. From these quantities, the radiation resistance and other relevant characteristics of the line can be directly obtained.

“…The basic theory leading to the dispersion relation, magnetostatic wave power, radiation resistance, radiation reactance and insertion loss for surface waves when the applied magnetic biasing field is in the direction of the Z axis (see Figure 1) has been previously detailed [1] [2], [6], [8], [12] This theory will here be outlined.…”

“…This systematic design method is then applied, in section 4, 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][29][30][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 section 5.…”

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 λ=500nm spin waves with an efficiency of -4.45 dB and a 3 dB-bandwidth of 134 MHz.
