Conductivity, Resistivity, or Sheet Resistance at DC

Some of the loss models allow you to choose which parameter you wish to use to calculate loss: Conductivity, Resistivity or Sheet Resistance at DC. The three parameters are defined as follows:

• Conductivity is the bulk conductivity of the metal. The default unit is S/m.
• Resistivity = 1.0 / conductivity. Resistivity has a default unit of Ohm-cm.
• Sheet Resistance at DC  = 1.0 / (conductivity * thickness)

where “thickness” refers to the metal thickness in meters. Sheet resistance at DC has a default unit of Ohms/square.
