How Can We Use Conductors to Receive EM from Space?

[shankar]

the concept of wave guide is built that the fielt can't get through the conductiong surface??

but we use conductors to get the EM from space how this could happen can sny one give the ans

Pretty simple really,

you see at high frequencies the currents are on the surface of the conductors. It's called the "skin effect".
