I think it's better you search about scattering form such objects and there are many books about scattering and you can find st in advanced electromagnetics books
This is wave guide theory.
Search any electromagnetic books by Krauss, Jorden etc.
There are numerical exercises in Krauss's book ( electromagnetics) which have problemms on walls, tunnels etc.
Added after 42 seconds:
If you want very very detailed theory then refer advanced electromagnetics by Balanis.
but I need, if there some specific measurements, where or some study concretely about wall, for example: graph for stone wall, brick wall, wet brick wall, plasterboard etc. Yes, it is electromagnetic theory, but i want to see some experimental measurements.
I do not want theory - i want to see some experimental measurements.
