Figure 2
Comparison between the MW imaging and FDTD simulation for the resonators with a straight wire and a tapered wire. The single points of the measurements are calculated by averaging an area of 4 × 4 pixels. (a) MW imaging of the straight-wire resonator and its simulation in (b), performed at a frequency of 2.945 GHz (\(\left|0\right\rangle \) → \(\left|+1\right\rangle \)). (c) MW imaging of the tapered-wire resonator and its simulation in (d), performed at a frequency of 2.7309 GHz (\(\left|0\right\rangle \) → \(\left|-1\right\rangle \)). The MW imaging of both resonators is performed at a MW power of 35.3 dBm. The white points in (a) and (c) are noisy points which are discarded from the image through a threshold applied to the FFT amplitude.
