We address the photonic spin-orbit coupling known from nano-optics and plasmonics in the microwave regime. The transverse spin and momentum of microwaves emitted by an excited magnetic dot are locked by with a fixed chirality when evanescent along . This field excites magnons in a nearby magnetic film in the form of directional beams that rotate with the magnetization direction. The exchange of these magnons through a magnetic substrate leads to a highly tunable strong coupling and entanglement between two distant nanomagnets.
