Beschreibung
Zusammenfassung:	The invention provides a wave-absorbing honeycomb with a pyramidal electric structure and a preparation method thereof. The wave-absorbing honeycomb is composed of wave-absorbing aramid paper coated with an absorbent and resin impregnated on the surface of the aramid paper. According to the electrical property design, the surface layer of the aramid paper is coated with pyramid-shaped wave-absorbing layer patterns in the breadth direction, and different wave-absorbing aramid paper with gradient electromagnetic properties is obtained; the wave-absorbing aramid paper is prepared into a corrugated structure through a template method, and the wave-absorbing honeycomb is prepared according to a lamination sequence designed according to electrical properties. The wave-absorbing honeycomb has a pyramidal electric structure along the cell direction, the electromagnetic property changes in a gradient manner, the wave-absorbing honeycomb has excellent wave-absorbing performance in an ultra-wide frequency range in the c
