From: The switching of strong spin wave beams in patterned garnet films
Photos showing the structures under investigation and demonstration principles of the two spin wave switchers. (a) 180° switcher, and (b) 90° V-type geometry switcher. Microstrip antenna (red vertical bar) placed on the surface of a YIG film under magnetic field H parallel to the antenna, and at the angle θ = 45° with respect to the line of square antidots. Microwaves in the antenna induce SWs propagating in the sample to the left (a) or right (b) with the field H in the negative or positive direction of the y-axis, respectively.
