Hi i want to know what is the relative permitivity value of black paint. Thank you.

Hi Berkeman,

From which source were you able to obtain this information. Could you please share it with me. Thanks

What sources have you found for reseaching your question? I seems like Google would probably be helpful, no?

Hi I have used google but was not able to find the values. Also i need relative permability, conductivity values, and magnetic loss values for black paint.

It depends on the paint. And I doubt you'll find values for most types of paint, you'll probably have to measure it yourself.

Why do you need this?

There are black paints and there are BLACK paints. Which were you interested in? https://mymodernmet.com/stuart-semple-black-paint/

I want to model how the electromagnetic waves propagates within a box with the inside wall painted black.

It is unlikely that the permittivity of the paint matters for that, but your description is still quite vague.
