Query: Magnonic Holographic Memory   Holography is a technique based on the wave nature of light which allows us
to utilize wave interference between the object beam and the coherent
background. Holography is usually associated with images being made from light,
however, this is only a narrow field of holography. The first holograms were
designed for use with electron microscopes and it was not until a decade later
with the advent of the laser that optical holographic images were popularized.
Multiple other fields have had major contributions made by using wave
interference to produce holograms, including acoustic holograms used in seismic
applications, and microwave holography used in radar systems. Holography has
been also recognized as a future data storing technology with unprecedented
data storage capacity and ability to write and read a large number of data in a
highly parallel manner. Here, we present a magnonic holographic memory device
exploiting spin wave interference.
