ABSTRACT:
A communications module includes an interior configuration designed to intercept, disrupt, and scatter EMI produced by the module during operation. The interior configuration may include an anechoic structure that includes a plurality of anechoic elements positioned proximate EMI-producing components within the module. The anechoic elements may form truncated pyramids, columns having rounded tops, cones, or other shapes. The anechoic elements may be uniform or non-uniform in size, length, or shape and can be arranged in a periodic, non-periodic, or random pattern. In some embodiments, the anechoic elements may include cast zinc metal, Nickel, and/or radiation absorbent material, such as a mixture of iron and carbon. In operation, EMI impinging on the anechoic elements is scattered by their surfaces until absorbed by the elements or other structures of the module, thereby preventing the EMI from exiting the module.
