Slotted honeycomb wave-absorbing structure

Abstract

The invention belongs to the technical field of electronic materials, and particularly relates to a slotted honeycomb wave-absorbing structure. N identical irregular gaps are formed in a periodic honeycomb structure, a space for embedding electronic modules such as antennas and radars in the honeycomb structure is provided, the design method based on honeycomb wave-absorbing structure embedding is achieved, namely, the honeycomb core is subjected to local hollowing treatment, a highly integrated electronic module is embedded into the core and is subjected to protection design, so that the spacecraft design has qualitative leap in the aspects of light weight and multiple functions. The key problem of the pre-embedded design is to evaluate the electromagnetic/mechanical strength of the slotted honeycomb structure, so that under a reasonable slotting method, the weight of the honeycomb structure is reduced, and the honeycomb structure has good electromagnetic/mechanical properties.
