Abstract
An anechoic chamber has a structure in which a dielectric plate is interposed between an electromagnetic shielding metal plate provided on an interior surface of the chamber and ferrite tiles serving as wave absorbing members, such that the ferrite tiles are located on an interior-side surface of the chamber. Screws serving as metal fittings are secured onto the electromagnetic shielding metal plate, and the dielectric plate is reliably attached to the metal plate by making use of the screws. Alternatively, the dielectric plates are attached to the steel sheet by means of adhesive such that the dimensions of each dielectric plate is made sufficiently smaller than those of a fixed size.
