FIG. 1.

(Color online) (a) Schematic diagram of the experimental set up. (b) The waveguide structure is a microstrip waveguide with a thin permalloy film under the signal line and the wave propagates in a transverse magnetic mode with the h field in the y direction.

FIG. 2.

Attenuated output power versus frequency for two angles of the magnetic field with respect to the long axis of the waveguide. The input power was always 34.5 dBm, and the static magnetic field is 220 Oe. The inset shows a top view of the waveguide and the static magnetic field.

FIG. 3.

Results of a macrospin calculation for the amplitude of my as a function of frequency. The input wave is at a frequency f1 = 2.5 GHz and is driven by an oscillating field with amplitude hy = 10 Oe. The static field is 220 Oe. Note that even a very small change in angle away from θ = 0 produces a significant signal at the 2nd and 4th harmonics.
