Sorry, I don’t understand your question. Try a heat transfer textbook or ASHRAE HoF.

Subject: Re: [EnergyPlus_Support] problem with thermal radiation
thank you for your answer
1-this solution that you said in reality is different form that i said.
because amount of radiation reflection inside layers is different from radiation refection at the internal reflective cavity what should i do ?
2- do you know where can i find the correct value of solar and thermal and visual absorption for materials?
thank for you time

The model for surface heat transfer in EnergyPlus is not what you seem to imagine. Trying to assemble an internal reflective cavity using Construction and Material objects does not work. You would need to develop equivalent properties for that portion of the assembly and collapse them into a single Material layer.
