Structural design and electrical performance simulation calculation of microwave absorption coatings

Since the application of electromagnetic technology, the investigation of microwave absorbing materials has been widespread concerned in the world. With the development of technology, the effect of microwave absorption technology is constantly increasing in the world. Up to now,the structural design and electrical performance simulation calculation of microwave absorption coatings play an increasingly important role in the preparation of microwave absorption coatings. The design and optimization of coating structure can directly improve the absorption performance. Nowadays, microwave absorbing materials usually have multi-layer structures such as impedance matching layer, absorption layer and bonding layer. Their reflection coefficients are determined by the thickness,magnetic permeability,and dielectric constant. Only relying on the experiments to study the influence of reflection coefficient must be inevitably resulted in a relatively broad and blind workload. Based on this, three kinds of microwave absorpt
