· 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 .

· Electrical resistivity represented by the Greek letter ρ (rho) is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity the more readily the material permits the flow of electric charge. Electrical conductivity is the reciprocal quantity of resistivity. Conductivity is a measure of how well a

• ### How to measure resistivity of a given sheet of material

· Generally for thin sheets we measure sheet resistance by using a three point or four point probe method. Then you can find the resistivity of the material by using a relation between sheet resistance resistivity and thickness of the sheet.
