[0002] In order to make electromagnetic wave absorbing materials have better absorption performance at low frequencies, the absorbing materials are often made very thick. Solid polyurethane sponge absorbing materials have a soft texture, and will become pointed when the thickness exceeds 1 meter. Therefore, absorbing materials exceeding one meter are usually made into hollow pyramids, with polystyrene plates as the skeleton inside and polyurethane sponge absorbing sheets wrapped outside. Since the polystyrene skeleton does not have absorbing performance, the absorbing performance of the hollow pyramid is worse than that of the solid polyurethane sponge absorbing pyramid of the same height.
[0003] Therefore, it is necessary to provide a new type of large hollow pyramid absorber, which absorbs electromagnetic waves by forming a skeleton with a first connecting plate and a second connecting plate. Utility Model Content

[0011] As a further preferred solution, the first sponge absorbing plate, the second sponge absorbing plate and the third sponge absorbing plate are all blue, and the first connecting plate, the second connecting plate and the top cover are all black-gray.
[0012] Compared with the prior art, the pyramid absorber provided by the embodiment of the utility model has the following advantages: 1.
