Materials that radio frequency EM waves can penetrate

[jaketodd]

Can radio waves penetrate steel? What about titanium? Maybe a characterization of what they can't penetrate would be more informative? ...Or a way to figure out what materials they can penetrate.

Thanks,

Jake

Look up 'skin depth'. It depends upon the resistivity of a metal and frequency. The best conductors provide the best screening. If you want very good screening, it's quite a difficult problem at some frequencies. RF can 'get in' through seams and doors in even the best screened enclosures.
