[0032] Multiple material baseplates are placed with a second or third absorbing material inside, then screwed together with a slot cover. The baseplates are adjusted along the adjustment openings and secured to studs on the top and bottom baseplate units with flange nuts. The first absorbing material is then embedded in the positioning slots of the metal shielding plate and placed between the first and second test bases. Long bolts are then screwed into the threaded holes in the first test base to secure the second test base. This allows the second and third absorbing materials to be replaced and maintained simply by unscrewing the slot cover, while the first and second test bases can be unscrewed to replace and maintain the first absorbing material. This allows the device surface to simultaneously perform multiple electromagnetic wave absorption tests.
