Abstract
Magnonics, or spin waves, are one of the most promising candidate technologies for information processing beyond complementary metal oxide semiconductors. Information encoded by spin waves, which uses the frequency, amplitude and/or phase to encode information, has a great many advantages such as extremely low energy loss and wideband frequency. Moreover, the nonlinear characteristics of spin waves can enhance the extra degrees of processing freedom for information. A typical spin wave device consists of a spin wave source (transmitter), spin wave waveguide and spin wave detector. The spin wave waveguide plays an important role of propagating and modulating the spin wave to fulfill the device’s function. This review provides a tutorial overview of the various effects of coherent spin wave propagation and recent research progress on a uniform spin wave waveguide. Furthermore, we summarize the methods of modulating propagation of a spin wave in a uniform waveguide, and analyze the experimental and calculated results of the spin wave propagation profile and dispersion curve under different modulation methods. This review may promote the development of information transmission technology based on spin waves.
