Cst loss tangent

WebFeb 19, 2005 · Yes it's correct that tan δ = σ/ωε. Loss tangent is the ration b/w the imaginary and real parts of the complex permittivity. where the complex permittivity can be defined as εc = ε-j (σ/ω) The valie of the loss tangent describes how lossy a material is, if σ » ω ε, it represents a very lossy material or a very good conductor. WebMay 22, 2024 · It is interesting to view what happens when the loss is greatly increased. Here this is done by increasing the loss tangent of the dielectric, \(\tan\delta\), to \(0.1\). This is much higher than that of any useful substrate. The reflection coefficient of the high loss line is shown in Figure \(\PageIndex{4}\).
