Experimental results. (a) Comparison of measured signals without (red) and with (blue) corrugations in the probe. (b) The same as the previous, but the peaks of both signals are normalized to unity. (c) Comparison of measured and theoretically predicted signals for the probe without corrugations. (d) The same as the previous but for the corrugated probe.
