(a) The trajectories of the circular motion in the co-field (green) and counter-field (blue) direction at a field voltage of 2 V_pp and with a laser irradiation of 360 mW. The radiuses of the trajectories vary with field frequency depending on the angular velocity of the circular motion. The time interval of each point is 0.07 s. (b) The velocity of electrothermal flow measured at a radius about 5 μm from the particle center gradually increases with field frequency from about 200 kHz to 2 MHz. Insets: (right) The flow pattern of rotating electrothermal flow. The images are accumulated for 50 frames and the time interval is 0.0068 s. (left) Image and schematics of the flow around the particle resulting from the momentum transference of electrorotation from about 10 kHz to 200 kHz.
