Theoretical Study and Computer-aided Design on the Loss Materials at the Oblique Incidence of Electromagnetic Wave

The formula of reflectivity of single-layer loss materials was presented at the oblique incidence of electromagnetic wave.Using the three-dimensional mesh method,the influence factors on the reflectivity was discussed,such as the incidence angle,the material electromagnetic parameters,the thickness of the material and other factors.At the same time,a computer-aided design for a given electromagnetic parameters of single layer structure was performed.The optimization results showed that the theoretical study will play a directional role for the design and application of experimental materials.
