$v$ :: is speed (ISO 80000-3: Space and time),

$l$ :: is characteristic length (ISO 80000-3: Space and time),

$σ$ :: is electrical conductivity (IEC 80000-6: Electromagnetism),

$μ$ :: is magnetic permeability (IEC 80000-6: Electromagnetism),

$ε_{r}$ :: is relative permittivity (IEC 80000-6: Electromagnetism), and

$μ_{r}$ :: is relative permeability (IEC 80000-6: Electromagnetism)
