Layout of the proposed sensing device for the aligned position (i.e., the CPW and the displacement sensing SRRs are aligned). The CPW strip and slot widths are = 1.67 mm and = 0.2 mm, respectively. The dimensions of the SRRs are () = 9.95 mm, () = 7.05 mm, () = 13.4 mm, () = 7.8 mm, = 1.67 mm, and = 0.2 mm. The considered substrate is Rogers RO3010 with dielectric constant = 10.2, thickness = 127 μm, and loss tangent = 0.0023. From [27], reprinted with permission.
