### Contactless methods of conductivity and sheet resistance

· The range of sheet resistances that can be measured in SiPDRs extends from 10 −1 to 10 4 Ω. The resistivity and sheet resistance ranges can be extended further toward even higher values by using a split post-dielectric resonator (SPDR) . For a 5 GHz SPDR the sheet resistance measurement range is from 3 kΩ to 10 MΩ .
