Which mechanism induces signal loss in microwave waveguides?

💡 Explanation

Dielectric absorption leads to signal loss due polarization requiring energy, and thus weakens the electromagnetic fields propagating through it, because this occurs in the insulation separating conductors; therefore absorption reduces signal transferred rather than changes in wall conductance which alter current paths.
