From: Nanoscale spectrum analyzer based on spin-wave interference
Schematic layout of the proposed spin-wave-based spectrum analyzer. The input signal is injected into a microstrip antenna, which generates spin waves on the patterned edge of an adjacent magnetic film. The interference pattern created by the spin waves is read out at specific locations using nanoscale loop antennas. The interference pattern is created in a way so that the frequency components of the input signal will become separated spatially.
