Supplemental Information for 3D-printed fixture for capacitance measurements of very low permittivity dielectrics

The SI.pdf file contains: Section S1- Technical drawings of the 3D-printed fixture; Section S2 - Advantage of the 3D-printed system as compared to a conventional, metal-framed fixture used for impedance measurements of ceramics; Section S3 - Validating the choice of the working frequency range: 10 kHz-72 kHz.
