Thermochromic tissue phantom (TCP) ablation experimental setup. (1) Signal generator (3 Vp-p, 500 kHz) was amplified by a (2) 20 gain linear power amplifier (60 Vp-p, 500 kHz) and (3) applied to TCP with a bipolar electrode and an insulating plate on top of the dielectric-coated electrodes to maintain its position. (4) Top view of the TCP ablated by the bipolar electrodes in 60 s. Note, the electrodes are covered with translucent dielectric material as modeled in silico in Fig. 1B.
