The dielectric response is studied for the frequency region, between the low-frequency plateau (LFP) and high-frequency plateau (HFP), and different types of transport mechanisms common in amorphous semiconductors and insulators. The response formula changes its characteristics depending on the shift in frequency range and type of conductivity/loss mechanisms. Therefore, deriving a unified formalism for these different regions and mechanisms can make understanding the anomalous transport processes easy. Thus, a composite formula called the Universal Law of Response (ULR) presents a novel contribution to combining all typed conductivity behaviors and makes this study a theoretical ansatz for transport processes. Therefore, all types of conductivity/conductivity-capacity (C/CC) responses between the low- and high-frequency plateaus can be categorized via some predefined parameters regarding the materials.
