Transmitted signal and efficiency of the antenna in excitation of the wave vector.

(a) A typical measurement of the transmission versus the frequency after 20 μm of propagation in 20-μm-wide, 20-nm-thick CoFeB waveguides. The applied magnetic field is μ0H = 75 mT. No direct current is applied through FM2. (b) Normalized Fourier transformation of the power delivered by our antennas (I2rf ) versus the wave vector (k) of the spin wave.
