Template:Classification of materials based on permittivity
From KYNNpedia
εr″/εr′ | Current conduction | Field propagation |
---|---|---|
0 | perfect dielectric lossless medium | |
≪ 1 | low-conductivity material poor conductor |
low-loss medium good dielectric |
≈ 1 | lossy conducting material | lossy propagation medium |
≫ 1 | high-conductivity material good conductor |
high-loss medium poor dielectric |
∞ | perfect conductor |
