Cross section of the microstrip waveguide. Showing the strength of the horizontal oscillating field due to a 1 W input signal. The Cu signal line is wide and the is in thickness.
(a) Output power measured by spectrum analyzer when the input is two small signals, both at −29 dBm, at frequencies and . (b) Output power when the input of is −2 dBm and has an input of power of −29 dBm. Note appearance of a new signal at and amplification the signal. (c) Output power when the input of is and has an input power of −29 dBm. Note the further amplification the and signals. (d) A comb of frequencies generated when and are both large and nearly equal. There is a 30 dB attenuator before the spectrum analyzer to avoid damaging the instrument.
Output power for different modes as a function of the power of the (10 GHz) mode. After the initial amplification of the power in the modes with increasing , there is a saturation or even decrease in output power as is further increased. The Py thickness is 300 nm.
Results of a perturbation calculation for the amplitude of for different modes as a function of the driving field. The thickness of the Py ribbon is 300 nm and width is . In the calculation , .
