Enclosed by an external metallic shielding to provide isolation from the outside environment. Interior lied with radio frequency/microwave absorbers and ferrite tiles to minimize unwanted multiple internal signal reflections inside the chamber to emulate an isolated, “free space” environment for radiation testing.
