Web9 mei 2024 · Thus, loss tangent provides an alternative way to quantify the effect of loss on the electromagnetic field within a material. Loss tangent presuming only ohmic (conduction) loss is given by Equation \ref{m0132_lt}. Comparing Equation \ref{m0132_lt} to Equation \ref{m0132_eratio}, we see loss tangent can equivalently be calculated as
