The honey-comb structure is non-conductive material, so we use different condition to causes it has the electrical conductivity and the magnetic conductive material, such as the pH value and temperature of the solution, and also change the size of honey-comb to increase the electromagnet wave absorbent. From this study, we can understand the different pH value and temperature will affect the nickel on the honey-comb surface structure and the different honey-comb size will also influent the electromagnet wave absorbent, such as the thickness and hole of honey-comb structure. We also plied the different size of honey-comb structure to discuss the absorbent of electromagnetic wave. From the research, we found that when the longitudinal honey-comb thickness and hole is 0.8cm and 1.0 cm respectively, the percentage of electromagnetic absorption bandwidth achieved 37%. And also plied the different size of honey-comb, when the lower layer longitudinal honey-comb thickness is 0.8cm and the hole diameter is 1.0 cm, the upper layer crosswise honey-comb hole diameter is 0.5cm, thickness is 0.8cm, the percentage of electromagnetic absorption bandwidth achieved 45%.
