Tables

Generic image for table
Table I.

EM-wave absorption properties of some recently reported nanocomposites. The optimal RL means the largest absolute value of the reflection loss, namely, the best absorption. The absorbent thickness denotes the layer thickness (range) for which . The absorption bandwidth is the frequency range in which can be achieved.
