Setup for the angular displacement measurement; (a) layer cross-section, (b) photograph of the fabricated CPW and ELC resonator, and (c) photographs of the experimental setup with positioners and a step motor STM 23Q-3AN. The parameters of the substrates are Rogers RO3010, = 11.2, = 1.27 mm, and = 0.0023; Rogers RO4003C, = 3.55, = 0.8128 mm, and = 0.0021; Teflon, = 2.08, = 3.5 mm, and = 0.0004; in-between air layer, = 1.27 mm, = 1, and = 0. ELC dimensions are mean radius = 8.05 mm, = 0.2 mm and = 6 mm, = = 0.2 mm, and = 0.5 mm. From [33], reprinted with permission.
