我们提出了一个可行性研究的逻辑电路利用自旋波的信息传输和处理。作为基于晶体管的架构的替代方法，具有自旋波总线的逻辑电路不使用电荷作为信息载体。在这项工作中，我们描述的一般概念的逻辑电路与自旋波总线，并说明其性能的数值模拟的基础上，现有的实验数据。对自旋总线中的信号衰减、信号相速度和每比特所需的最小自旋波能量进行了理论估计和数值模拟。的传输参数进行了比较与传统的电子传输线。自旋波总线并不打算取代传统的金属互连，因为它具有较高的信号衰减和较低的信号传播速度。然而，自旋波总线的潜在价值是电子电路和集成自旋电子电路之间的接口。具有自旋波总线的逻辑电路允许我们提供无线读入和读出。
We present a feasibility study of logic circuits utilizing spin waves for information transmission and processing. As an alternative approach to the transistor-based architecture, logic circuits with a spin wave bus do not use charge as an information carrier. In this work we describe the general concept of logic circuits with a spin wave bus and illustrate its performance by numerical simulations based on available experimental data. Theoretical estimates and results of numerical simulations on signal attenuation, signal phase velocity, and the minimum spin wave energy required per bit in the spin bus are obtained. The transport parameters are compared with ones for conventional electronic transmission lines. The spin wave bus is not intended to substitute traditional metal interconnects since it has higher signal attenuation and lower signal propagation speed. The potential value of a spin wave bus is, however, an interface between electronic circuits and integrated spintronics circuits. The logic circuits with a spin wave bus allow us to provide wireless read-in and read-out.
