Simulation of multiple composite coatings based on conducting plate and investigation of microwave reflectivity

A simulation of radar absorbing materials (RAM) with multiple composite coatings is given, including theory, methodology, and techniques. To illustrate the theory and method of multiple composite coatings, the basic tracking calculation method and pure-shape optimum are also introduced. In addition, the simulation process and examples with multiple coatings are described. Experimental results show that the simulation is effective, and the multiple coatings provide considerable microwave absorption. The multiple coatings used are types of broad-band coatings.
