Figure 7.6. Reconfigurable spin-wave switches at the grid points of the mesh.
In Figure 7.7, the cross-section of the reconfigurable spin-wave switch is
shown. A ferromagnetic film is divided by regions of diluted magnetic semicon-
ductor (DMS).
The reconfigurable switches work based on the same mechanism as a regular
spin-wave switch used in a crossbar architecture. The difference is that the
reconfigurable switches are controlled by four different control signals to form
15 possible interconnections, as shown in Figure 7.8.
7.5. SPIN-WAVE FULLY INTERCONNECTED CLUSTER
The architecture presented in this section is a nanoscale fully interconnected
architecture [13]. In this architecture, each node can broadcast using spin waves
to all other nodes simultaneously, and similarly, each node via spin waves
can receive and process multiple data in parallel. The significance of this design
is that the communication between the nodes can be done in constant time. This is
