EMW absorption characteristics

Terahertz wave band

EMW absorption characteristic is adjustable to suit your needs.

 

EMW absorption mechanism

Reflection wave

First reflection wave on the surface is interfered by the following  
reflections – 2nd, 3rd … reflection waves will absorb the first wave.
