Extended Data Fig. 3: Reconfigurability of the directional coupler by an applied magnetic field.
From: A magnonic directional coupler for integrated magnonic half-adders

a, The averaged spin-wave intensity for a frequency of 3.465 GHz as function of the external field for the first (blue circles) and the second (red squares) output waveguide of the directional coupler. b, Measured (circles and squares) and theoretically calculated (solid lines) normalized output spin-wave intensities at the first (blue) and second (red) output waveguide for different external fields. c–e, Two-dimensional BLS maps of the spin-wave intensity for the different external magnetic fields: c, B1 = 56 mT, d. B2 = 53.2 mT, and e. B3 = 51.3 mT. The right panels show the BLS intensity integrated over the red dashed rectangular regions.
