| Abstract: | The matching performance among the visible and near infrared coating, the low infrared emitting coating and the microwave
absorbing coating was investigated. Experimental results show that the resulting material is characteristic of wideband effect
ranging from the visible, near infrared and 3–5 μm, 8–14 μm infrared portion of the spectrum, as well as the radar region
from 8 to 18 GHz when these three materials form a layer-structure material system. The microwave absorbing ability of material
is hardly changed. The resonance peak moves towards lower frequency as the thickness of the visible, near infrared coating
and the low infrared emitting coating increases. This problem can be resolved by controlling the thickness of the material.
On the other hand, the infrared emissivity ɛ of the material system increases as the thickness of the visible, near infrared
coating increases. This can be resolved by increasing infrared transparency of the visible and near infrared topcoating or
controlling its thickness. The experimental resulting material system has spectral reflection characteristics in visible and
near infrared regions that are similar to those of the natural background.
