WebA lossy dielectric medium is defined as a medium in which the electric conductivity is not equal to zero yet it is not a good conductor. Setting σ ≠ 0 in Equation 1.12 leads to a non-zero attenuation constant (α ≠ 0). The general wave equations and the associated parameters expressed in Equations 1.12 to 1.22 therefore apply to lossy dielectric media.
