Abstract
An absorber for absorbing electromagnetic radiation including a first layer with hydrogenated carbon, and a second layer with carbon, and the first layer is less absorbing than the second layer.
Claims15
An absorber for absorbing electromagnetic radiation comprising:
- a first layer comprising hydrogenated carbon;
- a second layer comprising carbon;
- and
- one or more intermediate layers;
- wherein:
- the one or more intermediate layers are sandwiched between the first layer and the second layer;
- the first layer is less absorbing than the second layer;
- the first layer is an anti-reflection layer;
- the second layer is an absorbing layer;
- the first layer has a hydrogen content that is greater than the hydrogen content of the second layer;
- the first layer has a hydrogen content that is greater than the hydrogen content of the one or more intermediate layers;
- and
- the one or more intermediate layers has a hydrogen content that decreases successively from the first layer to the second layer.
