ABSTRACT:
The present invention relates to an electromagnetically anechoic chamber for EMC (Electromagnetic Compatibility) tests of electronic devices. The floor, ceiling and side wall of the anechoic chamber have panels of electromagnetic wave absorber having many ferrite tiles, and shield members comprising double layered shield members of copper sheets and iron sheets for absorbing and reflecting the foreign electromagnetic wave.
